The fold marker we use, `⋯`, isn’t rendered at the same size as the
editor’s font. Notice how the fold marker appears larger than the same
character typed directly in the editor buffer.

/>

When we shape the line, we use the editor’s font size, and it ends up
determining the element’s width. To fix this, we should treat the
ellipsis as a UI element rather than a buffer character, since current
visual size looks good to me.

Release Notes:

- Fixed an issue where the fold placeholder’s hover area was smaller
than the marker.
