Bug 1523562 [wpt PR 14872] - Deflake external/wpt/css/css-backgrounds/background-image-first-line.html, a=testonly

Automatic update from web-platform-tests
Deflake external/wpt/css/css-backgrounds/background-image-first-line.html

Wait another frame before ending the test because blink sometimes needs
another frame to update the background-image of ::first-line.
