Application crashes when shift + tab beyond the first element
dominikwilkowski opened this issue · comments
When running the counter example you can use the tab key to move between the two active elements. When you get to the end the focus is returned to the beginning. However the app crashes when you use shift + tab to go backwards.
On macos anyway.
