[Bug] Monaco renders four dots under some variables, and it cannot be disabled??

Monaco Editor Playground Code

void function(foo) {

    const x = fooo;
    const f = bar => barr;
}

Actual Behavior

There are four little dots under the first two characters of fooo and barr. These dots appear whenever the variable is similar but not correct, like a fuzzy spellchecker.

The IStandaloneEditorConstructionOptions do not contain an option for disabling the dots.

Expected Behavior

The IStandaloneEditorConstructionOptions do contain an option for disabling the dots.

Additional Context

I’m working on a webapp, reusing Monaco in a configuration that is graphically very plain. These dots could be a useful way to indicate issues. However, they’re not documented anywhere.

If I could customize when the dots appear (and maybe other things about the dots), they could be really useful for indicating and locating issues. As it stands, I just want to disable them.

Note: I’m sure I can find a way to make the dots invisible in CSS, but that would be a pretty nasty workaround, as the code would still be running in the background.

You can control that on the language side (I’m assuming JS)

monaco.languages.typescript.javascriptDefaults.setDiagnosticsOptions({
    noSuggestionDiagnostics: true
});

These three dots indicate that quick fixes are available (in this case a spelling quick-fix by typescript).
