NI on component owner for nomination decision.

[Blocking Requested - why for this release]: Functional regression on the new reference device (compared to the old one). The Outlook import page is just the Outlook website being rendered by Gecko. Moving the issue there.

This is a result of the customizer add-on screwing with the touch events.

This is a log of various gecko-side log things as I start a pinch. The log shows that the child process is seeing (1) a touchstart with one touch point, but the wrong block id, (2) a touchstart with two touch points which is correct, and (3) a touchstart with two touch points but coordinates that seem way off. The wrong block id is not really a problem since the APZ code is robust enough to handle that, but it's the result of the customizer addon holding on to the first touchstart event and then injecting that during the handling of the second touchstart. This results in the block id of the second touchstart getting applied to the first touchstart. The real problem is (3) where the last touchstart sets a bad target APZ and prevents zooming. I don't know where this is coming from, but disabling the customizer add-on makes everything behave as expected.

Actually my interpretation in comment 5 might be slightly off. I think the real problem might be that the first two touchstart events are getting targetted to the wrong frame.

Removing nomination as its specific to Windows Live site and needs more investigation.
