Publisher: Reset of attribute definitions on text/number field change

[iLLiCiTiT]

Current Behavior:

If callback of changes on instance does reset attribute definitions on instances, and the changed attribute is text or number field, it causes that the widget looses focus and user can't continue typing.

Expected Behavior:

It should keep focus of the widget.

Additional context:

The issue is that reset of attribute definitions does reset all widgets visible in UI to propagate possible changes/validation/enabled/visible state of wigets. To allow this feature we would have to compare currently available attributes in UI with new attributes and don't recreate them if are the same, and re-use existing widgets if definitions is the same.
