This PR fixes the people menu button's border being misaligned on
android.
There is a still a tiny tiny tiny sliver visible through the border,
which could be fixed in a future PR.
### Change Type
- [x] `patch` — Bug Fix
### Test Plan
1. Open a shared project on Android.
2. Place a visible *behind* the people menu button, so that you can
'see' the background-coloured border around the button.
3. Make sure the border is centered around the people menu button.
