Wrong titlebar shown after switching full screen windows with task switcher

[Captain Chaos]

After switching between the open maximised windows of an application using either the launch bar (by clicking on the application icon) or by spreading the windows (by pressing Super + W), the wrong titlebar is displayed at the top of the screen. Instead of showing the titlebar of the newly activated window, it shows the titlebar of the previously active window, greyed out.

This is especially annoying if you want to then drag the window you thought you activated to another monitor or workspace, as it will instead drag the previously active window. It also prevents you from using the menubar of the newly activated window.

Note that underneath the titlebar it does show the contents of the newly activated window, which also has the keyboard focus.

Possibly relevant information:
* I have three monitors
* I have focus follows mouse enabled
* I have the menubars of each window in their titlebars instead of at the top of the screen
