Filing a bug to cover the work described in this interop-2026 proposed focus-area: https://github.com/web-platform-tests/interop/issues/1123 This was a proposal from Mozilla's DOM team, but we anticipate that this includes a mix of DOM work and APZ work (and maybe wpt harness work? see below...) Test links: https://wpt.fyi/results/pointerevents?label=master&label=experimental&aligned&q=touch https://wpt.fyi/results/touch-events?label=master&label=experimental&aligned&q=touch I haven't looked through all the test failures in detail, but I'm noticing that there might be some WPT-harness work involved here too... Some of the WPTs (e.g. the various `pointerevent_touch-action-` tests) use a helper-function called `touchScrollInTarget` to synthesize a touch action, and most of those tests seem to have timeouts or other sorts of failures in Firefox right now. I wonder how much effort is involved in getting that to work properly. (Searching bugzilla for that function name, I found bug 1773393 comment 24 and bug 1797215 comment 0, which sound like that's known to not-currently-work and there's at least some moderate effort involved to get it working.
