Completions docs UI shows docs for wrong completion

Problem Description

What steps reproduce the problem?

1. Start Spyder in debug mode with Kite enabled and running (though I don’t think having Kite enabled/running is a requirement)
2. Type the following:

import json
json.dumps$

1. Highlight the first completion.

What is the expected output? What do you see instead?

Expected output: I would expect to see the docs for json.dumps.

Actual output: I see the docs for json.dump.

This issue seems intermittent and therefore leads me to believe this is a race condition in Spyder’s completions logic.
