You're right about the failure. I'm not sure how the commit you linked is related, unless Android 4 has the opposite issue of Firefox making it so you can't access inline style before computed for some odd reason.
Confirmed. This fixed the Dimensions tests for Android 4.
The only exception is Android 4.0, which is consistently failing (timing out) on all jQuery test suites (including Dimensions, but likely unrelated). Most likely something in the setup code of either jQuery or the testrunner is throwing it off.
