Steps to reproduce the problem:
1. set the two flags for cursor and input text accessibility features
2. check the boxes in Settings>>show advanced settings>>Accessibility
3. observe red and blue circles
4. go to flags and set all to Default
5. restart browser/or power cycle machine
6. red and blue circles persist [option for them is removed from accessibility menu, correctly]
3. 

What is the expected behavior?
red and blue circles disappear

What went wrong?
resetting flags to Default does not honor the 'unset" feature. Powerwashing to revert is a poor UX.

Did this work before? N/A

I am a TC in Chromebook Central.  No user reports of this as yet.  This is a lovely set of features, BTW, and will be most welcomed by vision-impaired users.  Bu other users should be able to unset easily.
