Bug 1823099 [wpt PR 39060] - De-flake two tests, a=testonly

Automatic update from web-platform-tests
De-flake two tests

These tests were timing out because window.screenX and window.screenY
were never set during the test run, leading to the code to wait 15
seconds before giving up trying to find them. But once it gave up,
it got the correct result, because there is no expected_screenX
or expected_screenY for these tests anyway.

Tests are:

external/wpt/html/browsers/the-window-object/open-close/open-features-non-integer-innerwidth.html
external/wpt/html/browsers/the-window-object/open-close/open-features-non-integer-width.html
