The mac-debug-wk1 bot seems to be in bad shape, exiting testing early.

LGTM, it is one of those patches where the testing is far more complicated than the change!

I believe this is set to false in WKWebsiteDataStoreStatisticsResetToConsistentState(), which is called between every test, so it should not be needed here.

Ditto, this can just be setEnableFeature(false, finishJSTest);

So true! But satisfying to make the change and immediately getting a failed test case.

Oh, I'll confirm and fix.
