Sliders don't seem to work on New Macs with New Safari.

Can't move analog slider using Safari on my Mac. I can see that they know I clicked on them. They get the blue highlight but they won't move. The interesting thing is, the round analog knobs work fine. macOS Sonoma 14.4 Safari 17.4

Make them move. I'd like them to work like others have them working.
