During real-world testing of this component, we found a couple of keyboard issues that should probably be addressed on the component side

• We should keep focus on input component after selecting something from the suggestions list.
  test case:
  1. start typing to open a list of suggestions
  2. press Tab to select first item from the list
  3. press Enter to apply suggestion.
  4. continue typing

Expected behavior: Focus should be on Input control. User should be able to continue typing

• In case of no suggestions we need don't need to set focus on empty list
  1. fill control with text without suggestions
  2. press Tab button

Expected behavior: Focus should be on next form control. It's probably true, but if I select somewhere in form focus returned back to EuiSuggest.
