Add crash test for bug 308359
https://bugs.webkit.org/show_bug.cgi?id=309558
Reviewed by Alan Baradlay.
This adds a crash test for https://commits.webkit.org/308356@main
where a floating first child button of a select element was later
not properly cleared. This can be reproduced by tweaking the HTML
UA style sheet with the following patch and repeating execution
of the crash test several times with ASAN or Debug builds
(e.g. by passing --repeat=50 to the run-webkit-tests script).
