Text Panel does not show as open in menu Window selection

I thought I saw this addressed some time back. But it seems odd that it is still not fixed. Tested in release 15.2 and Beta 5.4 Build 12.

Steps to reproduce:
    1. Open the Text Panel by any method (Window -> Text; double click a caption item; select Captions workspace).
 
Result: Text Panel is open, but does not show as open in Window menu.

Expected: The Text item should have a check indicating that it is open.
