[Feature Request] Allow the %activity% placeholder to work in the "Window title".replace section too

[Kishore96in]

I would like to display the name of the current activity along with the window title, and I was trying to use the option to replace the window title to do this, but it looks like the %activity% placeholder (implemented as per this issue for the empty desktop text) doesn't work for replacing the window title. I have attached images to show the issue.
