Description

[Ting-Yu Lin [:TYLin] (PDT, UTC-7)]

Reproduce Steps:
1. Open Messages app on B2G
2. Create a new message, and type arbitrary text into the message body
3. Long press to select a word in the message body.

Actual results:
The word under the finger does not being selected.

Expected results:
A word under the finger being selected.

Some analysis:
From the SelectionCarets log, the NS_MOUSE_MOZLONGTAP is handled by process 8737, which is the b2g process instead of the message app process.

qawanted for branch checks and a regression window if this is a regression.

I cannot reliably reproduce this bug following the STR. However this bug reminds me of bug 1166193, and I can only start to reproduce this bug after bug 1166193 has occurred.

Traits in common for this bug, bug 1166191, and bug 1166193: Memory specific (512MB; won't happen on 319MB, which all testers are on), touch events won't register on upper half of screen while keyboard is invoked.

Bug 1166193 seems to be reproducing more reliably, and it is no longer happening on latest.

Bug reporters please test on latest to see if it's still reproducible.

As can be seen from bug 1166191 comment 5, I also tested this bug on latest pvt. I can't reproduce this bug either.
