Ensure compositing test preference overrides are reset between tests Layouttests in the compositing/ directory override the default preferences to enable accelerated 2d canvas and enable mock scrollbars[1]. These preferences were not reset properly so tests following the compositing test could run with the compositing overrides. This patch forces preferences to be reset before every test. This flakiness was observable on the bots where tests would flakily fail with incorrect scrollbars: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=compositing%2Flayers-inside-overflow-scroll.html&showExpectations=true To reproduce this bug reliably, run: run-webkit-tests compositing/animation/state-at-end-event-transform-layer.html fast/canvas/canvas-render-layer.html --additional-driver-flag=--enable-slimming-paint-v2 --child-processes=1 which will fail. Running the tests individually passes.
