Pf4 select updates

[Hyperkid123]

Fixes

• pressing spacebar inside the searchable input toggled the menu (close/open)
  • the event is no longer propagated to input parent elements (toggle root)
• added a check for the type of filter value
  • opening a menu with set input value from the initial value caused the menu to crash
  • it was trying to run toLowerCase on an array
