Object type literal with string literal property in contextual typing position causes language service error on all literal type references

[DanielRosenwasser]

In a TypeScript file

interface SomeType {
    property: "foo";
}

/**
 * @type {{ property: "foo"}}
 */
const obj: SomeType = {
    property: "foo",
};

Request find-all-references on any string literal. This currently produces the following language service error:

<semantic> Response received: references (1602). Request took 7 ms. Success: false . Message: Error processing request. Cannot read properties of undefined (reading 'flags')
TypeError: Cannot read properties of undefined (reading 'flags')

Here's a simpler repro in a TS file

/**
 * @typedef {{ property: "foo" }} SomeType
 */

Just request find-all-references in "foo".
