Description Matt Woodrow 2023-05-18 18:45:11 PDT

RemoteLayerTreeDisplayRefreshMonitor::requestRefreshCallback dispatches a task to the main thread and sets scheduled to true.

When that task runs, it triggers the rendering update but doesn't set scheduled back to false.

Normally, the rendering update results in a commit to the UI process, and then we get a RemoteLayerTreeDrawingArea::displayDidRefresh callback, which sets scheduled to false (but also triggers a second rendering update).
