With 2.1.50 build on Apple Silicon, there is no consistent visual indication when the field sticky button is toggled and it appears inconsistent. Sometimes when I move from field to field in the editor, it will show the on state, when I return to the field I toggled previously, sometimes not.
I believe that the underlying sticky functionality works, but the visual indication does not.
and after clicking the sticky button on the field:
But if the sticky button was clicked then when the card is saved, the on state will be reflected on the new card, just not on the previous card on which the button was clicked.
