Bug 1510617 [wpt PR 14273] - Remove timeout from async_test for argument form., a=testonly Automatic update from web-platform-tests Remove timeout from async_test for argument form. (#14273) There're cases that the timeout is passing to async_test in the tests. They should be removed as well. Related: #11120 -- wpt-commits: 6911a29a5a8b1c27b9ec343935c132a1feb9d566 wpt-pr: 14273
