Screencast showing cog opening youtube, unable to get past the cookie banner due to onclick events not triggering

When using WPEWebKit cog browser on Wayland/Linux onclick events don't fire when using the mouse. All events work fine when using a touchscreen instead. Also `<a>` always links work fine.
I've tried WPEWebKit 2.46.x as well as 2.47.x, up to the lastest versions. The issue can easily be reproduced by installing `cog` on Archlinux (x86/64), but is also present when building all components from source.

See attached video for illustration. As you can see, onclick events for "Reject all" or "Accept all" don't work, while the subsequent click on the "More options" <a>-link does work. onmousedown and onmouseup work just fine. All works just fine when using a touchscreen instead of the mouse

I have encountered this as well, latest working version is WPEWebKit 2.44.x. I traced the issue to commit https://github.com/WebKit/WebKit/commit/62f87d3a9254d50d77d0feefab835c422c55e7eb.

I have done a bit more testing and this the issue is only present in Cog with the wayland backend. Gtk backend and MiniBrowser work fine.
