Semantic highlighting does not appear to work (due to theming)

1. I expect the first four characters to be highlighted but nothing happens.
2. There is no documentation really for any of the functions but releaseDocumentSemanticTokens in particular is not clear to me what I should be doing there.

monaco.languages.register({
    id: 'new'
});
monaco.languages.registerDocumentSemanticTokensProvider('new', {
    getLegend: () => {
        return {
            tokenModifiers: [],
            tokenTypes: [
                "keyword"
            ]
        }
    },

    provideDocumentSemanticTokens: () => {
        return {
            data: [
                0, 0, 4, 0, 0
            ]
        }
    },

    releaseDocumentSemanticTokens: () => {
    }
});

monaco.editor.create(document.getElementById("container"), {
    value: "12345678",
    language: "new"
});

I see. Thanks for the update @alexdima!

Is there some way to (easily) make the respective registerDocumentSemanticTokensProvider calls for Monaco to treat things the same way as in VSC?

So this issue is not 100% done.

Are there some plans to address this?

@aeschli @alexdima Now that microsoft/vscode#86415 has been finalized, can this be prioritized for April?
