Steps to reproduce the problem:
1. Open Settings > Accessibility
2. Check "Automatically click when the mouse pointer stops"
3. Select "extremely short (600 ms)" from drop-down menu after selecting any of the other menu options. 

What is the expected behavior?
If one of the other delay intervals is selected, a return to "extremely short (600 ms)" should work when re-selected. 

What went wrong?
Re-selecting the "extremely short" option from the drop-down menu after experimenting with any of the other delay intervals is not recognized. I'm stuck with either "short" or "very short," I'm not sure which. 

Did this work before? N/A
