Broken preview for highlighter duration #2
Description
Starting with 5583168, the preview of the highlighter duration behaves erratically. The preview only starts when you use one of the three other appearance sliders. I really don't know why. I tested it in Firefox Stable (131.0) and Firefox Developer Edition (132.0b2). Before 5583168, the behavior was also a bit... strange, because the ring disappeared for a random amount of time... but it always came back.
I’ve removed the live preview with c214c76 for this case until I find a good fix!
