Finn Evers 4280bff10a Reapply "ui: Account for padding of parent container during scrollbar layout" (#30577)
This PR reapplies #27402 which was reverted in
https://github.com/zed-industries/zed/pull/30544 due to the issue
@ConradIrwin reported in
https://github.com/zed-industries/zed/pull/27402#issuecomment-2871745132.
The reported issue is already present on main but not visible, see
https://github.com/zed-industries/zed/pull/27402#issuecomment-2872546903
for more context and reproduction steps.

The fix here was to move the padding for the hover popover up to the
parent container. This does not fix the underlying problem but serves as
workaround without any disadvantages until a better solution is found. I
would currently guess that the underlying issue might be related to some
rem-size calculations for small font sizes or something similar (e.g.
https://github.com/zed-industries/zed/pull/22732 could possibly be
somewhat related).

Notably, the fix here does not cause any difference in layouting (the
following screenshots are actually distinct images), yet fixes the
problem at hand.

### Default font size (`15px`)

Furthermore, for the second scenario, the popover would be scrollable on
main. As there is no scrollbar in the second image for this PR, this no
longer happens with this branch.

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.
