Browser / OS Minor UI quirks

[bpevs]

Describe the bug

There are some bugs that are showing up due to rendering differences on other platforms.

• Edge/Windows (Have not checked in other chromium browsers)
  • Favicon is maybe not centered correctly vertically. The auto-gen Github logo is slightly cutoff at the top.
  • Some emojis are not supported, or rendering improperly, but still show up in favicon selector.
• Windows, Firefox and Edge
  • Favicon selector width is slightly smaller, so some icons are being displayed only halfway on screen. Can still reach via scroll, but ugly. Cause looks like it is unsupported multi-byte strings, so both chars are being displayed discreetly. Can either cut-off via dropping 2nd char, or try to flatten/handle, see if it works. This is an extension of "some emojis are not supported"
