So I'm editing some cards through the UI. If I jump into the yaml editor and add in card_mod: with a bunch of CSS, after I bounce back to the UI editor then back to yaml, the lines are gone. I can leave the lines in the yaml editor and save from there, and they're kept. If I save in the UI editor the lines don't get saved. If I go to the raw file editor I do see the saved lines.
Am I the only one seeing this?
