Message:

Streamline test-and-clear operation for ContextMenu
​https://bugs.webkit.org/show_bug.cgi?id=197795
<rdar://problem/50473746>

Reviewed by Wenson Hsieh.

Rather than performing a check when entering the function, doing work,
then clearing the member variable, perform the check and clear in
a single operation. Only perform the selection if the menu exists.
