Almost the same code was on 3 different places.

Minor UI change: both new issue and merge request description textarea are now the same size. They were different sizes, so I picked an intermediate new size. The change is almost unnoticeable.

The pages that could be affected are: new / edit issue and merge request, diff notes and comments.

This continues the move for form DRYness as in https://github.com/gitlabhq/gitlabhq/pull/7678

cc. @razer6 if you get the time please check that I didn't break the feature =) A good indicator of non-DRYness are strings shown on the UI: when I saw that there were two occurrences of "Edit in fullscreen", I immediately git grep -C2 'Edit in and found this opportunity for DRYing.

I checked out the PR locally and tested it. Looks good Since this is directly related to a new introduced feature in 7.3 I merge this.

@cirosantilli Hey, I just saw an minor issue for the Edit in Fullscreen label. This is not related to this PR. If the text area for a not has focus (blue glow), hovering over Edit in Fullscreen overwrites the glow.

I tried to fix this, but do not see the error. Only the opacity is changed when hovering. Maybe you have a glue?

Hmm I haven't been able to reproduce on Firefox 32 Chromium 37. What view and browser are you on?

Hmm, Chrome 37.0.2062.122 on OSX also doesn't show this issue. I'm on Safari 7.1 on OSX 10.9.5.
