Linkified chat text can obscure GUI buttons to clicks

Though the linkified chat text doesn't visually obscure GUI buttons, they can precede them when attempting to click.

Steps to reproduce:
1. Take a screenshot (so as a create a link in chat)
2. Get in bed

Observed:
You can't click the button to get out of bed (save the bottom edge)

Expected:
Chat text visibly obscured by GUI shouldn't take precedence when clicking

Note:
The button highlights normally on mousing over, in spite.
