After viewing a message with tag and then viewing a message without tag a vertical scrollbar appears on the header pane. I can then switch to View Header All and then back to Normal, the scrollbar rests until I restart Shredder. When I view again a message with tags the scrollbar vanishes but is here again on messages without tags.

This is visible since landing of Bug 223132. But this bug is not the problem, as it works correct with all headers. Only when tags are displayed the problem occurs.

Reproducible: Always

Steps to Reproduce:
1. Mesage header in expandedHeaderView, normal mode, no scrollbar visible
2. View a message with tags
3. View a message without tags
Actual Results:  
Scrollbar in the message header appears

Expected Results:  
No scrollbar as before

fwiw, asking domi to delete the mail-tagfield#expandedTagsBox fixes the scrolliness; that doesn't happen by deleting any of the other headers. Undoing the delete retains the fixed state -- note that for the visible headers undo results in a blank value side until another message is loaded.

domi element outline flashing seems to claim a lingering label.tagvalue within the collapsed #expandedtagsBox is occupying space at the bottom left corner of the header pane.

looks like collapsed for the tag header means very narrow and invisible; the phantom tags stack up vertically, so if the last tagful msg you looked at had lots of tags you get a taller blank scrollspace. header values sticking around in collapsed headers seems to be the norm, usually their display just doesn't misbehave. here's a hack to collapse harder in the case of this header. could be put in themes but this seems to be a structural sort of issue so I didn't.

Lovely, thanks for figuring it out! I'll push it, switched to multiple lines so that style-of-the-file is only two different things instead of three, once the tree gets a little less colorful.

I've tested with the newest nightly. It works now as expected. Thanks to all.
Depends on: 513318
Philor, should this patch be backed out now that core Bug 513318 is fixed?
