(I've included a setting in my .vscode/settings.json file that I think will make my experimental class-regex work for you if you view /src/routes/+page.svelte in VS Code, but I've also included my global VS Code settings above as requested.)

Describe your issue

In the <script> part of a Svelte file, my experimental class-regex setting seems to be working in all ways except for the tooltips that should appear on hover. You can see in this video clip that I get autocomplete functionality and the little color-square for color-related classes, but no hover-tooltip:

(Note: this issue is not a duplicate of #636, since here I am using the experimental class-regex.)
