Speculative fix for flaky test

The test's history, e.g. on Linux[1], shows a very consistent pattern
of failing the first test case "touchstart event not received" and then
passing on a second attempt. My attempts at a local repo have not been
successful, but since it seems to be an issue with the state of things
at the beginning of the test and it involves input handling, it would
be good to see what effect waitForCompositorCommit has on the failures.
