QItemDelegate will continue receiving mouseover state after mouse has exited the widget

• Create a QTableWidget, fill it with any arbitrary data and enable mouse tracking
• Set a custom item delegate
• Override the delegate paint() method to switch on whether or not QStyleOptionViewItem::state contains QStyle::State_MouseOver or not

Expected behaviour: when moving over the table cells, the cell under the mouse is painted differently and when exiting the table, all cells look the same.

Actual result: If the mouse exits the table widget from the side of the currently hovered cell, that cell will remain active and its delegate's paint() method will continue having QStyle::State_MouseOver option flag (move mouse from bottom to top and upwards out of the widget).

Attached is a working code sample that demonstrates the bug.
