Mason Freed 62578c4931 Bug 1547665 [wpt PR 16546] - Adding a test for crbug.com/942555, a=testonly
Automatic update from web-platform-tests
Adding a test for crbug.com/942555

Unfortunately, due to crbug.com/895904 and crbug.com/567947,
this test isn't going to run on Android, which is where the original
bug occurs. But if crbug.com/567947 gets resolved, this test
can be enabled in SmokeTests.

Bug: 942555
