Hover state of QCombobox has not been reset

Hover state of QCombobox has not been reset

Click on the qcombobox to pop up a popup window, and click the left mouse button to make the popup window disappear. Repeat several times.

qcombobox is still in hover state. This problem only exists in wayland

I compared the logic under X11 and Wayland.

X11: popup menu -> right click outside the menu -> menu disappears -> received XCB_LEAVE_NOTIFY and XCB_ENTER_NOTIFY

At this point the control's WA_UnderMouse will be reset.

Wayland: Pop-up menu -> right-click outside the menu -> menu disappears without any leave or enter events.

The WA_UnderMouse state of Widget and QCombobox is not reset.

I'm not sure if this is a window manager bug, I tested it under kwin and weston, both.
