I don't know where you got the webkit-gtk:5 dependency from, but it should be :6 > import "gi://WebKit?version=6.0"; The upstream commit that made the change was https://github.com/sonnyp/Tangram/commit/92308c9422ae6d177962302b7f87ebd8683effd9 and it's included in v3.0. Please fix this so that I can remove webkit-gtk:5 with the next GNOME clean up.
I'm sorry. I realized I was looking at the 2.0 ebuild /o\ 3.0 is correctly depending on webkit-gtk:6. Sorry for the noise.
