Hi! WebKit is a complicated codebase, so I don’t think I can help you here. You may get some luck if you report this on https://github.com/qtwebkit/qtwebkit/issues.
Though, 5.212 series is based on a very old WebKit version, not sure if the author wants to fix any bugs there (he usually recommends trying qtwebkit-dev-wip branch but it's too unstable for packaging into Ubuntu). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1869765 Title: Problems dealing with Java Script promise in HTML To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtwebkit-opensource-src/+bug/1869765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
