Bug 1866876 [wpt PR 43376] - Add infra test that window.load happens …

…before reftest capture, a=testonly Automatic update from web-platform-tests Add infra test that window.load happens before reftest capture This adds a WPT infrastructure test to enforce that the harness waits for window.load before capturing reftest images. That allows testing like this: ``` <link rel=match href=green.html> <script> window.onload = () => document.body.append('test'); </script> ``` See [1] for conversation.
