I revert to eda2433181c9 in local build, the problem still happens.
So,  landing of Bug 503943 causes the problem.
Bug 503943 - Need a way to grab mouse events on arbitrary elements (implement setCapture/releaseCapture)

[Johnny Stenback (:jst)]

Olli, can you have a look at this regression?

Comment 2

[Neil Deakin]

Probably related to bug 559610.

[Olli Pettay [:smaug][[e-mail]]]

Bjarne, do you have any contacts from Hotmail team?

Comment 4

[Olli Pettay [:smaug][[e-mail]]]

Based on some testing looks like just having setCapture in the
element causes the problem - even if the implementation of that
method is no-op.

Comment 5

[Raul D @ Yahoo!]

Repro'd in Hotmail with Minefield 4.0b7pre 9.16.2010

Investigating a possible fix.

Attachment: a testcase for allowing setCapture during mousemove

Comment 8

[Olli Pettay [:smaug][[e-mail]]]

Attachment: patch

I'm still writing the mochitest for this.

Based on input from MS, this should be enough for them to fix Hotmail.

Comment 9

[Olli Pettay [:smaug][[e-mail]]]

Attachment: with mochitest

The test is a bit ugly, but should work.

After landing of patch pf comment #10,
Email item can drag over folder now,
However, the folder is not selected when drag email over the folder.
D&D still fails.

[Olli Pettay [:smaug][[e-mail]]]

that is expected. Hotmail team needs now to make a fix on their side.
(I was told the patch for Gecko should be enough for them to get
things working.)

[Olli Pettay [:smaug][[e-mail]]]

Marking this fixed based on the message from MS
"I've tested our fix on the latest nightly build of Firefox and it works fine. "

So I assume the fix in Hotmail code will be there soon.
