Clementine Plasma Tray Display

I’ve a new installation of Leap 15.2. I subsequently installed Clementine and it works, but the tray icon is behaving improperly.
When doing a mouse-over the tray icon pops up a window that seems to display raw formatting code. The status information (artist, track, etc.) is contained in the displayed code, so the communication is fine, but the interpreter seems to be offline or broken.
Any suggestions to fix this?

How is the setting for displaying that information from the Clementine settings?
Maybe even a screenshot would help in this case.
I use Strawberry so it is basically very similar, it is a fork from Clementine.

As far as I’m aware there is no setting for this tray application in Clementine. Other tray icons display formatted information correctly, so I’m guessing something got out of sync with the program developer and changes in Plasma. The information is there, it’s just not catching the formatting tags and implementing them but instead displaying everything as text. The same as if you were to ‘view source’ for a web page. I saw this happen in another install of another distro earlier this year so it’s not specific to OpenSUSE. Because of a number of bugs that were causing me problems in Plasma I tried out Cinnamon for a while, but now I’m back on Plasma for the last few days because I missed some of the functionality but it would seem the bugs are still there (I suspect they’re primarily related to the age of my video card, Radeon chipsets are old these days so drivers probably don’t get the attention of newer hardware).
