Comment 5

[Henrik Skupin [:whimboo][⌚️UTC+1]]

There was a change of the test name in testing/web-platform/meta/webdriver/tests/classic/perform_actions/pointer_mouse.py.ini:

- [test_move_to_position_in_viewport[default value\]]
+ [test_down_closes_browsing_context[with up\]]

I do not understand why this happened. We should not modify such entries with a wpt sync.

Sadly the patch landed on mozilla-central after it was merged to mozilla-beta. That means we need an uplift of the patch to mozilla-beta now as well.
