Fix checked state for the popup menu items in the events generated by them.

Fix checked state for the popup menu items in the events generated by them.

We incorrectly passed the sign-extended int id to ::GetMenuState() function
that expects an unsigned WORD id, so it never found the item if the WORD id
had the high bit set. Fix this by correctly passing the unsigned id to it.

Closes #11644.
