The algorithm for starting a transition requires us to examine the
before-change and after-change values of the property, without taking
any current animations into account.
..and delay static position calculation in IFC until trailing
whitespace are removed, because otherwise it's not possible to correctly
calculate x offset.
Containing block for abspos grid items depends on their grid placement:
- if element has definite grid position, then corresponding grid area
should be used as a containing block
- if element does not have definite grid position, then padding edge of
grid container should be used as a containing block
So offset should be adjusted for paddings only for boxes without
definite grid position.
The web server for WPT has a tendency to just disconnect after sending
us a resource. This makes curl think an error occurred, but it's
actually still recoverable and we have the data.
So instead of just bailing, do what we already do for other kinds of
resources and try to parse the data we got. If it works out, great!
It would be nice to solve this in the networking layer instead, but
I'll leave that as an exercise for our future selves.
This fixes an issue where document.write() with only text input would
leave all the character data as unflushed text in the parser.
This fixes many of the WPT tests for document.write().
...instead of directly mutating Gfx::Bitmap.
This change is preparation for using GPU-backend for canvas painting
where direct mutating of backing storage that bypasses painter is no
longer possible.
Our current text iterator is not aware of multi-code point graphemes.
Instead of simply incrementing an iterator one code point at a time, use
our Unicode grapheme segmenter to break text into fragments.
Instead of trying to locate the relevant StyleSheetList on style element
removal from the DOM, we now simply keep a pointer to the list instead.
This fixes an issue where using attachShadow() on an element that had
a declarative shadow DOM would cause any style elements present to use
the wrong StyleSheetList when removing themselves from the tree.
When a block container has `clear` set and some clearance is applied,
that clearance prevents margins from adjoining and therefore resets
the margin state. But when a floating box has `clear` set, that
clearance only goes between floating boxes so should not reset margin
state. BlockFormattingContexts already do that correctly, and this PR
changes InlineFormattingContext to do the same.
Fixes#1462; adds reduced input from that issue as test.
This is not that easy to use for test developers, as forgetting to set
the url back to its original state after testing your specific API will
cause future navigations to fail in inexplicable ways.
This patch implements `Range::getClientRects` and
`Range::getBoundingClientRect`. Since the rects returned by invoking
getClientRects can be accessed without adding them to the Selection,
`ViewportPaintable::recompute_selection_states` has been updated to
accept a Range as a parameter, rather than acquiring it through the
Document's Selection.
With this change, the following tests now pass:
- wpt[css/cssom-view/range-bounding-client-rect-with-nested-text.html]
- wpt[css/cssom-view/DOMRectList.html]
Note: The test
"css/cssom-view/range-bounding-client-rect-with-display-contents.html"
still fails due to an issue with Element::getClientRects, which will
be addressed in a future commit.
The current min/max zoom levels are supposed to be: 30% and 500%.
Before, due to floating point error accumulation in incremental addition
of zoom-step into zoom-level, one extra zoom step would get allowed,
enabling user to zoom 20%-to-510%.
Now, using rounding, the intermediate zoom-level values should be as
close to the theoretical value as FP32 can represent. E.g. zoom-level of
70% (theoretical multiplier 0.7) is 0.69... .
The IPCs to request a page's text, layout tree, etc. are currently all
synchronous. This can result in a deadlock when WebContent also makes
a synchronous IPC call, as both ends will be waiting on each other.
This replaces the page info IPCs with a single, asynchronous IPC. This
new IPC is promise-based, much like our screenshot IPC.
If we already destroyed our timer during destruction, and then curl
tries to flush its timeouts when we tear down the multi, we can just
ignore the timer callbacks.
DOM nodes that didn't have a layout node before being removed from the
DOM are not going to change the shape of the layout tree after being
removed.
Observing this, we can avoid a full layout tree rebuild on some DOM node
removals.
This avoids a bunch of tree building work when loading https://x.com/
