Quote blocks forum copy&paste usage!

Hi.

Something changed as right now there is no way to copy part of text as selection goes away by Quote mini popup.

Normally it works like this - you can select word in the middle of the sentence and copy…:

This is how it works today on TO forum - I have tried to select “/dev/” without success as Quote poped up :frowning:

Working for me in Firefox 50.0.2.

I’m on Safari 10.0.1
It worked fine last week.
