1509959 - Add a test for bug 1502010

Status: RESOLVED FIXED

(Core :: Panning and Zooming, enhancement)

Description

[Kartikaya Gupta (email:[e-mail])]

Spinoff to add a test for bug 1502010. The scenario in question is when an element has touch-action: pan-y, and the user does a horizontal pan action on the element, the web content should get a series of pointermove events tracking the motion. Prior to the patch in bug 1502010 we would dispatch a pointercancel pretty much right away. This could result in broken content effects like JS-based carousels not working, etc.

Hm, looks like we are still getting events after the test ends. I thought I handled that better in this second version but I can robustify even more.

Updated patch. Here's another try push just for the pesky macOS verify jobs: https://treeherder.mozilla.org/#/jobs?repo=try&group_state=expanded&revision=c0afdb66808adb85a2650cfd2d6f9081f68bf04d
