problems with richtext widget
There appears to be some bugginess using the spell checker in the richtext widget which don't manifest in the standard text widget.
Any word selected to correct its spelling seems to most frequently override the first word in the text field (but not always). Quite frustrating... At the same time it would be useful to have a means to undo the operation.
BTW, there seems to be an issue pasting text as well, giving the warning 'TypeError: deserialize() takes 6 positional arguments but 7 were given'
