checkJs error for indirect JSDoc param tag

[DanielRosenwasser]

TypeScript Version: 2.6.0-dev.20171015

// @ts-check

function Foo() {
    /**
     * @param {string} wat
     */
    this.bar = function(wat) {

    }
}

Expected: No error
Actual: JSDoc '@param' tag has name 'wat', but there is no parameter with that name.

Probably due to #18777.

Any chance this will be fixed in TS 2.6? This is a big blocker for us upgrading to 2.6, as we use JSDoc in many places.

As a workaround, I'm using @ts-ignore.

Yeah, it's certainly #18777 -- the type is correct, it just issues a spurious error.

Fix is up at #19355

@sandersn Thanks for getting this fixed so quickly!
