FWIW (maybe not anything) I get

$ xdg-mime query default x-scheme-handler/mailto
claws-mail.desktop

and clicking on a mailto link in a Fancy-rendered message opens a Claws
composition window for me.

I don't know how any of this works, so I won't give any advice.  All
I've ever done to set a default handler was go through KDE's system
settings as described earlier in the thread, once under KDE4 and then
again after moving to KDE5.
