Avoid capturing MenuItem instead determine checked state from toggled signal
Summary:
Due to JS lambdas menuItem is being captured by reference, and as such
the call to menuItem.checked returns the checked state of the last item
in the for loop. Instead of adding to the capture this patch uses the
supplied boolean from the QMenuItem::toggled signal.
Also unlike Array.concat Array.splice alters the current array, we don't
want to create a new var.
BUG: 376826
Test Plan:
Debug of menuItem.text showed we were capturing the wrong thing
Clicked window into multiple activities and unticked them. All worked as intended
