Increase the compact reference overflow to 20px and slightly raise its
mono font to improve legibility and vertical alignment. Add explicit
square sizing and an aspect-ratio for the repo tab close control so
its icon and layout remain consistent across breakpoints and overrides.
Use !important on the size rules to ensure they take precedence.
- bump .compact-ref-overflow height and font-size for alignment
- add fixed sizing and aspect-ratio for repo tab close button
