I've tried out the new Clear Data Filters Action and it has some undesirable behavior. When I click my Button to clear the filter, all the Filter Widgets in active use just vanish from the Page. See video.
The data is unfiltered (so I guess it technically works), but only if I go into the Settings for the Action and specifically target the Datasource. The All Data option does not work on an Output Datasource.
If I was a user hitting a Clear Filters Button, I would not expect to never be able to make a new Filter. This cannot be the intended design. If it is, this needs to be redesigned, because this Action has extremely limited utility in its current form.
