[javascript] TextMate themes don't seem to apply to all keywords

[tSte]

Since last update the default VS Code dark theme has changed (I like the old one because I just don't want bright red colors on the dark background). So I tried (first time I have to admit) create (or modify) a theme via http://tmtheme-editor.herokuapp.com/

Resulting theme is a modification of Visual Studio Dark (uploaded as .txt since .tmTheme is not allowed)
Visual Studio Dark Modified.txt

tmtheme-editor online interprets theme as follows:

VS Code however does not interpret theme identically:

Please note that this is my first contact with this stuff - I'm not sure if this is an issue related to VS Code of tmtheme-editor

Okay I found out that class, super and extends are interpreted as 'invalid.illegal' - why are those interpreted that way? My jsconfig.json contains compiler options for ES6...

"compilerOptions": {
"target": "ES6",
}

The problem is that our JavaScript tokenizer isn't supporting ES6 yet.

I am not sure if ES6 is the problem here... for example the "let" or "const" keywords are classified correctly. But the "new" keyword is not. Object keys are considered (if I am not wrong) to be constants. Document and Array objects poses also different colors.

Looking at your code example we need to get ES6 back to work.
