fix(modal,flyout): autofocus fix for input and non focusable elements
Browse files Browse the repository at this point in the history 
Autofocus was not taking care of invisible inputs (in dropdown)
classname observer was too sensible and accidently triggered autofocus (search, dropdown, form validation)
autofocus should only focus inputs, otherwise focusing the module directly for focustrap
click into an input when window was refocused triggered autofocus instead of respecting the clicked input
