Description

The "Start Timer" button of the Time Tracker in the editing issue page doesn't have enough space for the European Portuguese translation for the word "Timer" ("cronómetro"), but I've noticed that other languages have the same issue, like German, Spanish and Turkish.

The left and right padding of the button text is 1.5em. Perhaps making it 1.2em would solve the issue.
