I am running epiphany Web 46.0 as packaged by openSUSE Tumbleweed, and ldd confirms that it is linked to /lib64/libwebkitgtk-6.0.so.4, which rpm verifies is from libwebkitgtk-6_0 as packaged by Tumbleweed, and gsettings is version 2.80.0 in package glib2-tools, and regardless of what number I put at the end of the command line

$ gsettings set org.gnome.desktop.interface text-scaling-factor XXXX

epiphany looks absolutely identical, from its address bar to its icons to its website content text to its layout. I take it that is not the case for you? How would you like me to proceed -- is there any concern that my setup is not appropriate for testing, casting doubt on https://github.com/WebKit/WebKit/pull/26938 ? I will say I _do_ see a significant difference in behavior, with layout much improved, when I compile and run with that code (which I have only done with the minibrowser, not epiphany, but I could try to link epiphany with the resulting libraries if you feel it would be helpful). Thank you very much for the guidance -- I definitely would like to contribute, and improve layout I am seeing from WebKitGTK, but I also don't want to harm anything if I am not seeing proper behavior of existing code on my end.
