[SOLVED] Konqueror can't open locally saved web pages

Hi, the title says it all. I'm running Plasma 5.27.10 on Mageia 9, and I've set up Dolphin to open locally saved HTML files with Konqueror (23.04.3). However, it complains that it can't handle "application/x-extension-html" (whatever it is, instead of text/html). These are rather simple webpages.
It doesn't make any difference clicking in Dolphin or trying to open them from within Konqueror itself.
I know Konqueror is a dinosaur, but it's nice to browse local files without launching a full browser with all bells and whistles...
