The container appears to be null for certain elements such as the
"update your browser" box when clicking on the document during certain
parts of loading. Skipping it works fine, but should obviously be
fixed, so it prints a debug output when this happens.
Google Docs focuses a "text event target" iframe using Window.focus on
the iframe's contentWindow. Doing so makes the iframe's document the
focused element we have to fire text events at. However, in the top
level browsing context, the focused element is still the iframe, so we
have to repeat the keyboard event steps but with the iframe's nested
browsing context instead.
process_the_iframe_attributes already causes a navigation, so this
would cause a double navigation and blow away any setup that JS may
have done from events fired in process_the_iframe_attributes.
This was a missing spec step. This prevents it navigating to
about:blank, which will blow away the document and thus any setup that
was done in the iframe load event.
These are required for hit testing the document in Google Docs. If they
aren't defined, the Google Docs hit test code will add undefined to
certain values, causing them to turn into NaN. This causes NaNs to
propagate through their hit test code, which eventually makes it
infinitely loop.
When volume is zero it is not necessary to go through the mixing loop.
The zero-filled buffer can be written directly to the device, instead,
similar to the muted case. Tested by using the piano app and the main
volume control.
C++20 can automatically synthesize `operator!=` from `operator==`, so
there is no point in writing such functions by hand if all they do is
call through to `operator==`.
This fixes a compile error with compilers that implement P2468 (Clang
16 currently). This paper restores the C++17 behavior that if both
`T::operator==(U)` and `T::operator!=(U)` exist, `U == T` won't be
rewritten in reverse to call `T::operator==(U)`. Removing `!=` operators
makes the rewriting possible again.

Previously each emoji had its own symbol in the library which was then
referred to by another symbol. This caused thousands of avoidable data
relocations at load time.
This saves about 122kB RAM for each process which uses LibUnicode.
Previously the s_decomposition_mappings variable would refer to other
data in s_decomposition_mappings_data. This would cause thousands of
avoidable relocations at load time.
This saves about 128kB RAM for each process which uses LibUnicode.
Should use the min_content_height function for calculating the height of
content. Thanks to previous commits, are able to use the width of the
column for this calculation.
Should use AvailableSpace to get the grid width instead of
box_state.content_width().
This change was imposed on me by the compiler as in a future commit I
will remove the only reference to the available_space parameter.
