What steps will reproduce the problem?
(1) Browse as guest >> chrome://md-settings/manageAccessibility and check any checkbox and observe.

Expected: Should be able to enable accessibility options
Actual: Instead nothing happens on enabling any of the accessibility options.

Note: This works fine in signed in user and works fine in normal settings of guest mode.

Raising this as non-regression as in M53 stable browser crashes on going to advanced section in guest mode

@dmazzoni: Please confirm the behavior
