Description Jeroen Zwartepoorte 2024-03-20 02:47:46 PDT

The codepen in this blog post https://nerdy.dev/steal-this-popover-starter-kit (https://codepen.io/argyleink/pen/JjzqXee) has a bug on STP 190 where the "tip" contents of the popover is missing when you open the popover for a 2nd time.

This is probably related to `@starting-style`, since I can't reproduce this bug in Safari 17.4 and that does not support `@starting-style`.
