I still have this issue on safari 14.1. The caption is still displayed on top but an invisible space shows up at the end. And when I look at this with the devtool it's highlighting the caption.

I forgot to tell that in my case it's like that. But if I use the given codepen on Safari, I still have the same bug as @Denys !

Right. It seems that Safari 14.1 doesn't include the fix. Please try the latest Safari Technology Preview 125. https://developer.apple.com/safari/technology-preview/
