Hello,
I've tested version 2026-01-23 and I confirm your changes.

1. Switching back between format  and \uea67 works now ok.

2. HTML structure doesn't changed after events.

3. CSS class is changing according to state. But you missed

.fontIconFocusedDown

on above list. :)
So here is full list for future reference:

.fontIcon,
.fontIconOver,
.fontIconDown,
.fontIconFocused,
.fontIconFocusedOver,
.fontIconFocusedDown,
.fontIconDisabled {
...
}

Thanks your update.
Best regards
