screen shot of yahoo email Inbox showing *white space gap* in between headings/listing
The yahoo mail Inbox listing does not render correctly.
What happens is that there is a very large white space gap
(several scrollable screens worth of white space) between
the yahoo menu heading and the listing of mail Subject lines.
The amount of white space displayed is different for different email accounts.
There are many error messages in the console log of the same ilk:
... so there may be some new security fencing recently introduced
somewhere within r118394-r118466 that yahoo mail violates.
GMail is also broken by the same revision, bug 87461.
This should be fixed by a rollout of the offending patch.
