Now I find this: /usr/share/applications/mimeinfo.cache:text/html=abiword.desktop;firefox-esr.desktop;google-chrome.desktop;kfmclient_html.desktop;org.gnome.Epiphany.desktop;org.kde.kimagemapeditor.desktop; /usr/share/applications/mimeinfo.cache:x-scheme-handler/http=firefox-esr.desktop;google-chrome.desktop;kfmclient_html.desktop;org.gnome.Epiphany.desktop;
So Abiword does not pretend to be an http: protocol handler, just an application supporting HTML files.

Likely you have changed file associations for HTML files from KDE System Settings. Try to move away ~/.config/mimeapps.list or comment out text/html entry there and Abiword should pop back.
