gpui: Recalculate list layout after the window has been resized (#51414)
Closes #51417

I noticed this bug in the settings menu where when I opened the settings
menu, I could not scroll down through all the available options, eg. on
the initial page I wasn't able to scroll down to privacy. When I saw
that no one else had reported this issue, I figured it may be due to my
setup, and it turns out that using Aerospace, the window manager I use,
was what made this bug visible to me. Because aerospace resizes the
window right after it launches, the originally computed heights for the
list are incorrect, meaning the scroll bar is the wrong size as well.

in the relevant code there was a comment that says "If the width of the
list has changed, invalidate all cached item heights" which wasn't
incorrect per-se, but it just invalidated them without triggering any
re-computation, causing incorrect scroll bars.

My intuition is that window resizes/events that change the width of the
list bounds are fairly rare, so there shouldn't be a large performance
hit from the change.

Also implemented a test that directly showcases the behavior, if you run
the test without the change it fails, as the max_offset_for_scrollbar
will be wrong.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
