Reporter: Can you try the latest nightly build? I think this is a duplicate of bug 100511. That bug is fixed in the recent nightly builds.
Reassigning to HTML Form Controls - email@example.com: what build id of Mozilla/N6 are you using? Please include the build id in any bug report - thanks. As firstname.lastname@example.org says, this sounds like a bug that has recently been fixed with the bug 34297 landing - for example, compare bug 100511, bug 105074. If the bug still occurs with an up-to-date build, could you please attach a reduced testcase to this bug via the "Create a new attachment" link above? That would speed things along considerably.
The bug was detected on 2001101117 (I thought Bugzilla would capture that). I haven't tried the nightly builds but I will.
this looks like a dup of bug 104904
I have confirmation that this works properly in the 2001-11-13.03 daily build. Sorry about the useless bug submission.
Ok, per reporter's comment, -> WFM
