Using arrow keys when using highlightFirstSuggestion prop and multiSection is broken

[asafigan]

Example

1. Focus on the input field
2. Use the arrow keys

Observed behaviour: Highligted suggestion is different than the text field. Highlight order is weird. Example: skipping suggestions, and going out of order.

Expected behaviour: Suggestion highlighting should be linear

Even without using those props I've found that the selection often doesn't move or jumps mutltiple at once (sometimes backwards).
