This release changes the way focus is managed in some edge cases:
- then content inside FocusLock is updated in a way that the previosly focused element no longer focusable (or deleted)
- before: focus moves to the body
- now: focus moves to the nearest sibling (of any), or first element on the block
- when the focus lock is active inside iframe
- before: it will (endlessly) fight with focus lock that might be present in the parent frame
- now: the parent frame always wins
- explanation: as for parent focus inside iframe means iframe is focused, and it will prevent another element on the same page from being focused
