Bug with faded background on Bitbucket's issue tracker

Steps to reproduce:

1. Go to an open issue on the issue tracker.
2. Click "Resolve", close modal window by hitting the Esc button.
3. Click "More", let the dropdown menu stay open.
4. Click with left mouse button in free space outside of more.

As a result, the entire page will have faded background – there is no way to get rid of this except by reloading the page.
