1. Delayed accessibility events sent when a view subtree changes may be be delivered after accessibility is disabled leading to a crash. It is possible that accessibility was disabled while we were waiting for the timeout before sending the event. Added a check before dispatching. 2. When refreshing a cached node the accessibility node info cache was not using the correct bypass cache argument value and as result was not getting the latest node but its cached value. We really want to get the latest state to update the cache. 3. The debugging cache integrity verification logic was incorrectly removing nodes from the cache while doing its work. 4. Removed the comments for some debug logging. bug:9857067 Change-Id: I20ee1a6ffa65ad35457b51d3f2dc0bc5d8d784e6
