I nuked my Fedora 40 machine, installed Fedora 41. At the same time, I switched from Xfce (after using it for over a decade) to KDE. I am absolutely adoring the KDE experience, but there is one weird thing that I can't figure out. I hope someone can point me in the right direction.

I use a fair number of Chrome applications (PWAs - see https://support.google.com/chrome/answer/9658361) for things like Google Calendar, Google Chat, Google Messages for Web, and Slack (I know about the Slack app for Linux, but I've had wonky results with it, so I prefer a PWA).

Now, under Xfce in Fedora 40 and previous versions, I could middle click on a PWA and it would lower just fine, just like any other application. But under KDE, when I middle click any non-PWA app, it lowers as expected. If I middle click a PWA, it does nothing. I believe that it's because PWAs don't have title bars, and the "middle click to lower" action works on title bars.

 So my question is, how do I get a middle click to lower a PWA app in KDE? I have not been able to find any articles on how to enable title bars in Chrome apps, although I may be searching using the wrong terms. Any pointers?
