Half a minute is more than enough for the test to finish even in the slowest
browsers and in case of starving the PHP FPM process pool, one has to wait
for only half a minute to try again.

Android 2.3 doesn't support stopImmediatePropagation; jQuery fallbacks
to stopPropagation in such a case.

PHP sleep function accepts time in seconds, not milliseconds; the previous
value was starving the PHP FPM process pool.

The "document ready when jQuery loaded asynchronously" test fails all the time
in iOS7 and sometimes in other browsers. Bumping the timeouts *might* help
these other browsers to be less flakey here.

Fixes #13997

It's not easy to find a CSS property that is implemented even in
ancient browsers and that returns a consistent result among browsers
when passed through .css(). color didn't work since Firefox normalizes
it an empty value to rgb(0, 0, 0).

The workaround to be able to change !important styles broke the browser
keeping the old CSS value if the new one was rejected. Patching it would
involve a significant perf hit (~33%) so the initial patch needs to be
reverted instead.
