When the timer fires, you should check if there's a pending layout and let the layout trigger the AX update. This is for the cases when you have different type of mutations coming the same time with the focus change. 
1. focus change
2. focus change
3. tree mutation
4. some other style mutation
In this case your timer will fire before the layout timer and you should really just not do anything at this point.
