### Steps to reproduce
* install Live Chat (`im_livechat`)
* Go to Live Chat > click any channel
* Under Widget, Click the copy button for the first link
If you're on firefox, nothing will happen (text won't be copied).
On chrome, you will get a traceback saying `Failed to execute 'write' on
'Clipboard'`.
### Expected behavior
The text should be copied to the clipboard, and a tooltip should appear
to confirm that.
