Provide go-to-definition on unresolved shorthand properties

[DanielRosenwasser]

interface Foo {
    /**
     * Hallo this is docs
     */
    yadda(): void
}

let x: Foo = {
    yadda/**/
};

Imagine that I am typing some code. I realize I don't remember what yadda is supposed to look like, so I run go-to-definition on yadda.

Problem

Go-to-definition doesn't work, because at this point yadda is a shorthand property, so go-to-definition tries to look for a local named yadda that doesn't exist.

As a workaround, I often end up writing

interface Foo {
    /**
     * Hallo this is docs
     */
    yadda(): void
}

let x: Foo = {
    yadda: undefined!
};

just so I can go-to-definiiton on yadda, which really sucks.

Expected Behavior

We should resiliently try to pick up on the original definition and jump there.
