As per the stale github issue:
Describe the issue you are experiencing
The docs about the Picture Glance Card state “The entities on the right side allow toggle actions, others show the more information dialog.”
In my opinion, buttons should fall into the group of “toggle actions”, however they are shown on the left and open a “more info” dialog when tapped. To make a button inside a Picture Glance Card pressable the tap_action has to be set to action: toggle.
Describe the behavior you expected
If adding a button entity to a Picture Glance Card, it should show up with all the other actionable items on the right, and I shouldn’t have to manually set the “tap_action” attribute to make it pressable.
