Unable to reproduce in 57.0.2987.110 for Chrome on Linux, seems to be fixed on the last update since I was able to reproduce before I restarted Chrome.

Right, another difference is I was repro'ing it with my chromebook last time.

Was able to repro in 57.0.2987.110 for Chrome on Mac, although one workaround is to just switch to a different tab and back, and the UI will update.

Accessibility: Fix color enhancer disable option

Color enhancer extension should be completely disabled when the user
selects the option to disable it. Previously we used the identity matrix
instead, which can cause problems when there is a filter regression, and
users have to completely remove the extension and refresh.

Also align with the way high contrast is using filters and css.
