Steps to Reproduce:

1. Open larger HTML file that includes <script></script> tags
2. Use Inspect TM selectors
3. Inspect HTML code after a </script>, & the reported (& visually highlighted) code is JavaScript, but should be HTML.

Does this issue occur when all extensions are disabled?: Yes

Thanks for all your hard work! :)

Is this a dup of #70614

Please add the source sample..

Not sure if related.

Any Save As... YouTube HTML page will work it seems. Can't test too much with these files, since VSCode lags out sometimes. (Perhaps related or another bug?)

If you /really/ want me to attach / link a file, I can.

Thanks for the tip, I can reproduce with the youtube html page.

Yes, the embedded JavaScript code isn't correctly understood by the grammar and prevents the rest
of the page to be correctly highlighted: Dup of #20488
