Press Right key to focus inspector tab AR: Focus outline in buttons on devtools toolbar isn't consistent with focus outline in devtools tabs: focus outline in tabs is placed right near the borders of the tab rectangle, but buttons have some indent between focus outline and the visual borders of the button ER: Focus outline should have the same "layout" as in tabs This is regression from bug 1286872. Regression range: > https://hg.mozilla.org/integration/fx-team/pushloghtml?fromchange=6b9dae7e278dcd38d0b1c221ca9420931dfac7fd&tochange=626f03d8438fb7f7bbc778d80672037bd95ac0f7@ Tim Nguyen :ntim (use needinfo?): It seems that this is a regresion caused by your change. Please have a look.

:bgrins, any opinions on this one? Not sure how severe it is / whether it warrants regression tracking.
