Behavior of pv_name property change #3797

Description

A user is pointing out that for the Array widget, changing the pv name property with a rule does not trigger the expected change, i.e. it does not connect to a different PV.

Investigating this I conclude that it looks like only three widgets support a change in the pv name property such that the widget connects to a different PV: text update, spinner and text input.

If this is truly the case, is this by design or simply not yet implemented in other PV-aware widgets?
