I suspect the issue is that we are not running helper_zoom_with_touchpad.html with the same prefs as other tests.

The increased content response timeout is particularly important for tests that perform preventDefault(). This timeout is a browser intervention to aid responsiveness (we give the webpage a time limit to call preventDefault() or not, and if the time limit is reached we assume it did not). Tests often run on slow machines / in memory-constrained environments so some timeouts need to be increased to keep tests reliable.

My theory about the reason for the failure in comment 1 may have been wrong.

I've investigated this a bit further. The cause of the failure appears to be that we register a non-passive wheer listener here, and then immediately after send native events which we intend to preventDefault() with that listener, here.

The native events can arrive at APZ before the transaction that informs APZ about the existence of the non-passive listener. If APZ does not know about the listener, it handles the events right away rather than enqueuing them while it waits for a content response.

This can be fixed by adding a call to await promiseApzFlushedRepaints(); between registering the listener and sending the events.
