WGLMakie plots result in "Unable to connect" when running Pluto in a container

[littlebenlittle]

I'm not sure if this an issue with Pluto with WGLMakie.

Start by running Pluto in a container using the official julia image OR the pluto image

docker run -ti --rm -p 1234:1234 julia

] add Pluto
using Pluto
Pluto.run(host="0.0.0.0")

Running the attached notebook causes the plot to display an "unable to connect" web error.

There does not appear to be any useful information in the browser console as to why this is happening. It would be helpful to catch these kinds of errors and provide some debug info.
