Highlight does not stay on Google Music's notification controls #408
Description
When attempting to pause a song from the notification bar, the HUD can be used to access individual controls, but after a moment, the highlight on the node reverts again to its parent, making it impossible to use the control.
This seems to be related to the constant "Node is null!" message in the log output. Seems there is either unnecessary triggering of a11y events by the a11y service, or there is some kind of unnecessary polling of the UI that resets the highlight.
