Field name (or value) suggestion list jumps to first item, even if an item is already selected/highlighted

[coffee-squirrel]

Expected Behavior

If a user has "arrowed down" to highlight a field name/value suggestion, and the field name/value suggestion list (or the suggestions up to and including the highlighted field name/value) doesn't change, the highlighted name/value should not reset to the first item in the list.

Alternatively: if the user has highlighted a field name/value suggestion the suggestion list should not be modified/updated.

Current Behavior

Given I have fields source_priority, source_type, and source (among others), if I type so and arrow down to highlight source (skipping source_priority and source_type) I see the highlighted suggestion jump up to the first item in the list (presumably after /api/search/validate completes-- ~80ms). Something similar happens for field value suggestions.

I believe this started after we moved from 5.0.x to 5.1.x.

Steps to Reproduce (for bugs)

1. Have a 5.1.2 environment
2. Have fields with a common prefix
3. Open your browser dev tools and watch XHR requests
4. Start typing that field name prefix, and after the initial suggestions appear arrow down past the first entry and wait
5. Note that after the /api/search/validate request completes the first suggestions gets highlighted

Context

This makes working with field name/value suggestions annoying, since the UI wipes out the suggestion I arrowed down to.
