3329 // - Input ownership is automatically released on the frame after a key is released. Therefore:
3330 // - for ownership registration happening as a result of a down/press event, the SetKeyOwner() call may be done once (common case).
3331 // - for ownership registration happening ahead of a down/press event, the SetKeyOwner() call needs to be made every frame (happens if e.g. claiming ownership on hover).
3332 // - SetItemKeyOwner() is a shortcut for common simple case. A custom widget will probably want to call SetKeyOwner() multiple times directly based on its interaction state.
3333 // - This is marked experimental because not all widgets are fully honoring the Set/Test idioms. We will need to move forward step by step.
