After enabling Pointer Events, we should launch pointerdown event immediately when the screen is touched. Now, the pointerdown is launched when the finger or pen removed from the screen, which is the timing of pointerup.
If we set browser.tabs.remote.force-enable to true will fix this issue on e10s and APZ are enabled platform.
Hi Stone, would you please follow Ben's comment 1 to move this bug forward? Thanks!
