Embedded javascript string with // have unexpected behavrio

[alexr00]

Original from @Namorzyny in microsoft/vscode#105779

Steps to Reproduce:

1. Input some code like: <input type="button" value="text" onclick="location.href='https://www.google.com'">
2. The code will display as a comment:

This only occurs if the // is in the string. The character before the // will get invalid.illegal.newline.js.

This issue doesn't occur with just the javascript grammar, only when its embedded like this.

Thanks to some investigation from @mjbvz, the issue appears to be here:

html.tmbundle/Syntaxes/HTML.plist

Lines 341 to 359 in 0c3d5ee
