Syntax coloring partially missing for JavaScript blocks inside HTML file

[UweKeim]

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

(I've even removed all user settings from "C:\Users\ukeim\AppData\Roaming\Code\User\settings.json" and restarted VS Code with no improvement)

• VS Code Version: 1.86.2 (user setup)
• OS Version: Windows_NT x64 10.0.22631

Steps to Reproduce:

1. Open this attached HTML file into VS Code.
2. See that syntax coloring is not applied to all JavaScript code inside the <script> block.

Please note that for a short amount of time (approx. half a second) right after opening the file in VS Code, the syntax coloring is correct and then flashes (and stays) immediately to wrong.

OMG, I figured out the reason.

My attached HTML file has this in line 152:

<script>var $z = $.noConflict(true); var showFrameTimeout</script>

When removing this line, the whole HTML syntax-coloring is correct, again.

After digging further, I found out that the missing semicolon (;) right after showFrameTimeout is the cause of the whole mess.

To fix this, I rewrote the line 152 this way:

<script>var $z = $.noConflict(true); var showFrameTimeout;</script>

After that, everything looks correctly colored.

This was the most important semicolon in my whole developer's life of over 25 years 🥰.

Still, I would love if VS Code would not stumble (and fall) over one missing semicolon.

Yes, this is an annoying issue but unfortunately not easy to fix
