Application icons no longer display on application windows when share screen

[mcdonamw_ews]

I recall in the past, when I go to share my screen, the application-specific windows used to have the icon of the application on the lower left or right corner.  That icon no longer displays.  Has anyone else noticed this?  Is this a known issue/design choice in some recent update?

That icon was really helpful in identifying the specific windows I want to share.
