These timeout tests pass locally (bug 270408 resolved the crash expectations). Not sure what's going on. Perhaps they don't have the time they need on the bots?

Fixing this as part of bug 287181. The problem is that the bots don't have ENABLE(TOUCH_EVENTS). *** This bug has been marked as a duplicate of bug 287181 ***
