> I was able to workaround the issue by either removing the reverse proxy, or
> use the reverse proxy and decode the the `order%5B0%5D%5Bdir%5D` to
> `order[0][dir]`.
> Is it possible that this params gets encoded twice when enabling
> `spark.ui.reverseProxy`? just like the https proxy that was fixed
