• VSCode Version: Version 1.19.1 (1.19.1)
• OS Version: 10.12.6 (16G1036)

Steps to Reproduce:

1. Type as per normal e.g. 'actor', see code completion list
2. Notice that fully matching value 'actor' is not matched, but the next closest value is 'ActorMgr'
3. (Side effect) Press Escape to avoid matching undesired value

Expect:

If I type in an exact match, then that should be the value I will get after tabbing / entering, not the next closest match.
