Vivaldi in Wayland Mode

Running Vivaldi in Wayland Mode on Gnome (with --ozone-platform-hint=wayland OR by setting flag in browser), causes Wayland to fail to launch.

$ vivaldi
[14223:14223:1123/] Failed to load wayland client libraries.
[14223:14223:1123/] Failed to initialize Wayland platform
[14223:14223:1123/] The platform failed to initialize.  Exiting.

Brave, another chromium browser, works fine. Any ideas?
