REGRESSION:

I was able to reproduce this bug on the reported platform running the test as follows:

run-webkit-tests -1 --debug --use-gpu-process --accelerated-drawing fast/events/wheel/redispatched-wheel-event.html

I was able to bisect a possible regression point using the flakiness dashboard (265781@main). In my attempts to reproduce the issue on multiple platforms, DumpRenderTree kept crashing on WebKit 1, which caused the test to fail at all tested commits. The changes at 265781@main appear to be directly related to the failing test, which is likely contributing to the failure; however, this may indicate a larger issue with DumpRenderTree.
