comma-spacing and space-before-function-paren are conflict in type

[Austaras]

Don't know what's the root cause of this problem, I guess it's the parser

What code were you trying to parse?

function x<R extends Record<string, (this: any) => any>>(fns: R) {
    return fns
}

when eslint config includes

"comma-spacing": "warn",
"space-before-function-paren": ["warn", "never"],

What did you expect to happen?
code shall pass lint

What actually happened?
code violates rule comma-spacing when

function x<R extends Record<string,(this: any) => any>>(fns: R) {
    return fns
}

and violates space-before-function-paren when

function x<R extends Record<string, (this: any) => any>>(fns: R) {
    return fns
}

Same issue as in #364, except it's a different rule.

[Austaras]

well, thanks for the explanation, hop it will get fixed soon

[bradzacher]

comma-spacing has not been fixed yet

[Austaras]

IMO comma-spacing doesn't need a fix since generic parameters are supposed to have a space after comma(like prettier does) so as you said this rule "just work"

[bradzacher]

sounds good!
