Lint warning doesn't appear until script is edited

[the0neWhoKnocks]

Not sure if this is an Atom thing or an issue with this plugin... or both.

• Currently, if I add an unused rule within a style tag, no lint warnings appear.
• When I start to edit anything within a script tag, the lint warning appears.
• Same behavior to fix the warning. Remove bad code, go to script tag, add space or whatever, then the linter kicks in.

This is almost certainly an issue with Atom. I'm guessing the ESLint integration has an optimization where it doesn't re-run linting unless the script tag is updated. I haven't used Atom in a few years, so if you find something in the configuration for their linter or linter-eslint packages that disables this optimization (or whatever needs to happen) a PR would be appreciated.

I've got linter-ui-default, linter-eslint, and linter installed. The only one that has any settings that key off of file changes is linter. I've got everything enabled in linter

There is a note for Lint on Change that states:

Lint files while typing, without the need to save (only for supported providers)

Not certain what supported providers refers to specifically though. Is it this plugin, the language server, or something else?

I'll debug linter and see if I can figure out the answer to what supported providers is.

After some debugging, I found a comparison happening in linter

function Ae(e, t, i) {
    return !(t && !e.lintsOnChange) && i.some((function(t) {
        return e.grammarScopes.includes(t)
    }))
}

e.grammarScopes always equaled ["source.js", "source.jsx", "source.js.jsx", "source.flow", "source.babel", "source.js-semantic"].

While editing within a style node, i equaled ["*", "source.svelte", "source.css", "meta.property-list.css"].

While editing within a script node, i equaled ["*", "source.svelte", "source.js"].

So the linter was kicking in while editing script sections because of the presence of source.js.

I wasn't able to determine where i was being defined, but e.grammarScopes was defined within linter-eslint. Once you click in that input, it fills it in with the defaults, I appended source.svelte, and am now getting realtime lint warnings.

Also, I used to have the core: customFileTypes stuff set up, but removed it while debugging and haven't noticed anything not working. Not sure if that doc is out of date, or required for another use case, but perhaps it can be removed.
