1268734 - It's not possible to copy selected text in console if I start selection below console messages (focus stays in command line)

Status: RESOLVED INVALID

(DevTools :: Console, defect, P3)

Description

[arni2033]

>>>   My Info:   Win7_64, Nightly 49, 32bit, ID 20160426044609
STR:
1. Open data:text/html,<style>a{b:c;d:e}
2. Open console (Ctrl+Shift+K), enable all errors/warnings
3. Click on the empty area below console messages
4. Start selecting text below messages and finish selecting text over the messages after 5 seconds
5. Press Ctrl+C

AR:  Text isn't copied, because console still has the focus
ER:  Text should be copied to clipboard = console shouldn't be focused

I have tested your issue on latest Nightly build (49.0a1) and managed to reproduce it. I have followed steps 1-6 and the text isn't copied. I've also performed a regression and this are my results:

Looks like the following bug has the changes which introduced the regression:

I think this was caused by bug 1239992, and finding real regression range is impossible, because at that moment text selection from empty space was unavailable because of bug 1260839. If I apply the same CSS fix in userChrome.css that fixed 1260839, it should be possible to find regression range.

I haven't mention it yesterday, because I had no time for that (and somehow thought it was obvious), so I'm sorry. I'll try to do the described trick today evening or hide this comment if it won't work.

Even with fix for bug 1260839 applied (comment 2), the regression range is the same as said in
comment 1. So it's definitely regression from bug 1237368.

We don't have this empty space at the bottom anymore with the new design (and if you're in the input, it makes sense to not being able to select anything outside of it)
