tims 34d0b57945 editor: Fix inline Git blame not visible on long lines due to overflow (#23374)
Closes #18702

This is take 2 of [my previous
PR](https://github.com/zed-industries/zed/pull/19555), which was closed
due to inactivity and merge conflicts.

**Cause**: 

The editor's horizontal scroll width only considers the longest line in
the buffer, using `layout_line` for `longest_row`. The inline blame
width isn’t included in it because it is just a decoration on top of the
line (think of like CSS absolute) and not part of its actual content.
This causes blame to overflow.

**Solution**:

Along with `longest_row` width we also add that line's inline blame
width for scroll width calculation. We also have to add some padding
that is between inline blame and line's content.

**Alternate Solution**:

In my previous PR, instead of adding the inline blame width of the
longest line for scroll width calculation, I used the inline blame of
the current line the cursor is on (since we only see the blame for the
current line). I added that to the current line's width, giving us the
full width of that row. Then, we compare that row's width with the
longest row width and use the max of the two for the scroll width
calculation.

While this solution seems clever, it's overly complicated and could
cause issues, like the scroll width changing every time you move the
cursor up or down. I don't think we should go with this, but I'm open to
suggestions.

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.
