STR_1:
1. Open http://example.org/
2. Click on identity block
3. Hover mouse over ">" button in identity panel

AR:  Border takes ~80% of height
ER:  Said border should take 100% of height (of the button) when hovered. References of good styling:
     Zoom level toolbarbutton, Cut-Copy-Paste toolbarbutton in overflow panel and Australis Menu,
     2 sync buttons, "Customize", (?) and "Exit" buttons in Australis menu.

Full list of elements with separators that don't change height:
- terrible oneOffButtons "improvement" shoved into search bar and urlbar
- all <tree> elements w/ new styling, for example about:config, about:preferences#applications
- identity block (STR_1)
