Improve completions with --checkJs turned off

TypeScript Version: 3.1.0-dev.20180725

Code

/**
 * @typedef {object} I
 * @property {number} m
 */

/** @returns {I} */
function f() { return { x: 0 }; }
const x = f();
x.

Expected behavior:

Get completion for m only.

Actual behavior:

Get completions for I, f, and x. None of which are properties.

As I pointed out in my last comment of #25579 I was wondering why I am presented with a list of suggestions scrolled to its end rather than its beginning. That suggestions list apparently shows the least significant results first while I have to scroll to the top to see the completions that refer to the actual type. I don't mind all the extra suggestions (as they are partly correct and hard/impossible to infer correctly from context) - I do mind, that I don't see the most reasonable suggestions right at the top of the list. Suggestion sort priority? Maybe I am missing a config? Although I think this can be considered pretty much the expected default behaviour.
