On Windows64 with KBM, moving the mouse over empty space (outside any
button) would clear the Iggy focus entirely. After that, pressing arrow
keys did nothing because Flash had no starting element to navigate from.
Two changes here:
- Don't set focus to IGGY_FOCUS_NULL when the mouse hovers over empty
space. The previous hover target stays focused, so switching back to
arrows keeps working seamlessly.
- When a navigation key is pressed and nothing is focused at all (e.g.
mouse was already on empty space when the menu opened), grab the first
focusable element instead of silently dropping the input. The keypress
is consumed to avoid jumping two elements at once.
This makes mixed mouse+keyboard navigation feel a lot more natural.
You can point at a button, then continue with arrows, or just start
pressing arrows right away without having to hover first.
