But you don’t press it, right? Since the hover colour is red, which indicates a danger. I’ve never accidentally deleted a post when expanding the ellipsis however, even if I did, I’d be able undo the action so although it seems bad you’ve hovering over a delete button its easily reversible.
As a site admin a solution to this would be to change the post menu site setting. This allows you to change the order of the post action menu. Ergo, when you expand the ellipsis you’d be hovering over a different post action. @HAWK 's point above still stands: its customisable.
