I’m seeing this strange behavior in 0.31.2, when hovering my line+bar card in dashboard. Not seeing it, if I only view the question.
Currently the card is half-width of the dashboard. If I change the width, then the strange behavior is still there, just shifted which columns creates the misplacement.
I didn’t notice it in earlier versions, but I’ve made several updates to all my cards, since 0.31.2 now fixes the date formatting among other things.
