Is it possible to override the e-mail client in Falkon to point to webmail (something like: https://support.mozilla.org/en-US/kb/change-program-used-open-email-links#w_using-webmail-services) or is that under the control of System Settings > Default Applications (where I cannot seem to find a plasma-wide solution there either)
I did find an old request for it in System Settings: https://bugs.kde.org/show_bug.cgi?id=148765 Given its age, I have greater hope for a solution in Falkon than in System Settings.
Git commit db9d506cf5c554947cfaefa3b290d275b7372b27 by David Rosca. Committed on 28/01/2019 at 16:54. Pushed by drosca into branch 'master'. Add support for Navigator.registerProtocolHandler() It is now possible to eg. register webmail to handle mailto: links. If a site asks to register protocol handler, it will be available in site info widget (right click on web icon in location bar).

So, if I hover over David Rosca in this bug in the field Assignee: David Rosca I can see this is a mail-to link. But I cannot see how to find the site info widget. I am now running Application version 3.1.0 QtWebEngine version 5.12.3
