// Set up for public-facing IsItemHovered(). We store the result in DC.LastItemHoveredAndUsable.
// This is roughly matching the behavior of internal-facing IsHovered()
// - we allow hovering to be true when ActiveId==window->MoveID, so that clicking on non-interactive items such as a Text() item still returns true with IsItemHovered())
// - we don't expose the flatten_child feature that IsHovered() has, which is only used by the window resizing widget (may rework this)
// FIXME-OPT: Consider moving this code to IsItemHovered() so it's only evaluated if users needs it.
