Thank you!

In general, the way GeckoView handles protocols is very different than on desktop, so our current approach was flawed/broken and leads to breakage like this.

So, this should be fixed for next release, but, in the meantime, from about:config, you can simply set network.protocol-handler.expose-all to true.
