comment draft lags when defocusing tab

[nedtwigg]

• open a comment
• type some stuff into it
• click the gitcasso popup
• BUG: the draft is not there
• close the popup and open it again
• now the draft is there.

The sequence of events is:

• open popup
• popup sends GET_OPEN_SPOTS to background
• background replies with GetTableRowsResponse
• because popup has focus, the tab lost focus
• tab notices and sends LOST_FOCUS event with updated draft
• but the rows were already sent

Workaround: if you defocus the text area manually by clicking somewhere else in the tab, and then click the popup, then the popup is up-to-date right away.

this is also a great opportunity to rerun tryToEnhance to grab updated titles and stuff. As long as the unique_id hasn't changed it's a simple win. If the unique_id has changed then it's more complicated...
