But locally, I can reproduce way back from that (r213000). So it's quite a mystery what happened. I don't see any notices of us upgrading the bots around that time. 1294406 3 ap 2017-04-04 23:32:10 -0700 As I reproduce locally, the first iteration always freezes. ResizeWithHiddenContentDoesNotHang: did layout ResizeWithHiddenContentDoesNotHang: calling setFrame ResizeWithHiddenContentDoesNotHang: returned from setFrame ResizeWithHiddenContentDoesNotHang: waiting to end animated resize 1295153 4 ap 2017-04-06 17:46:31 -0700 Rolling back r214391 fixes this (thanks Tim!) 1295158 5 ap 2017-04-06 17:53:59 -0700 Disabled in http://trac.webkit.org/r215080.
