In new message reader header pane, clicking on more-button of to-header (or any header for that sake) to expand a long list of contacts (200 in my case) causes a delay of 3-4 seconds before the expanded list of contacts shows up.

This bug was extracted from  Bug 460605 comment #9 as per Ludovics advice.
In bug 460605, similar delays when handling many contacts (= many DOM nodes) were observed in case of right-clicking a contact for context menu.

However, I just realized there are other problems with the header (like missing scrollbar, missing captions (from, to, etc.). Does anyone else see such probs? Otherwise I suspect something is wrong with my setup, maybe because i had message header tweaks installed (Bug 466025 -  explore message header tweaks and variants for tb3) [and polish], so right now it's a mess.

Reproducible: Always

Steps to Reproduce:
1. Mail with 200 contacts in to-header (Ludovic has a my private sample for Bug 460605)
2. click on more-button to expand list of to-contacts
3.
Actual Results:  
expanding the list of 200 contacts takes about 3-4 seconds (find my machine config in bug 460605 comment #9)


Expected Results:  
DOM nodes or whatever you use to display the contacts should be read in advance for the currently active mail so that when user clicks more-button, the whole list of contacts can be displayed immediately regardless of the length.
Thanks for filing; this is helpful.  I don't see the other problems you described, would you attach a screenshot?
Dan, you've got a mail.

Thomas, do you still see this in beta 4?  Similar bug was recently closed.

Dan, I sent a private email to you concerning an issue (unrelated to this bug) on Tue, 15 Sep 2009 21:34:50 +0200. Did you get it?

The other problems (missing things in header) are gone, were probably extension-related.

I still see a 1-2 seconds delay when clicking more-button, until the rest of addresses actually shows up. So it's less noticable than it was before, I guess.
That's for the version as below, I didn't download tb3b4 yet.

FWIW, Dan is focused on release blockers presently and this is not a blocker. So I'll chime in since I was looking at the other bug, to say I doubt this will get fixed in version 3.

If you see 1-2 sec that's really not bad, so demoting to minor. However, using 20090915 build I see variability in my testing that I can't explain. The message from which I created this testcase took 26 seconds one time, but last one took 10 sec. testcase takes about same amount of time.

Hm, even with "search everywhere" I don't find your answer, nor in the spam of TB nor server. Could you send it again and let me know here the time of sending?
R U sending with your mozilla.org account that is linked with your bugzilla profile here?
Is this fixed after bug 560695 has been checked in? [try 20100515 or later]

The message reader is being largely rebuilt for version 115. So this issue is will not be fixed for the current version 102.

If the problem exists in version 115 when it becomes available in July please file a new bug. You can also evalute the rebuilt reader in 3-4 weeks by trying a beta build.
