Copy Chat / Cursor Display Issue
EDIT by @Simpy: so, this is back! lol there is an issue when you try to copy something in an edit box but the click area makes it click somewhere above because of the issue mentioned in this ticket that was reintroduced in a recent WoW patch.
As of 7.3 ElvUI has been showing the cursor in the Angry Assignment text window incorrectly which is more than frustrating and makes it close to impossible to edit. While having no other addons but ElvUI and ElvUI config enabled this is still an issue, disabling them it works.
