Description
This is also an issue with compile warnings (not sure if they go to stderr).
In 18.1 & 18.2 when it panics it displays the error from the panic & from the compilation. However, it does not display any output from the program. Giving output of the program shows where the program got up to before it panics and gives a better understanding of what is going on.
In 4 & 5.1 it tells the user try to fix things/try to break things in order to see compiler warnings. These compiler warnings are not seen, instead just the program output is shown. This could be fixed by when running the rust code to turn those warnings into errors, but not sure if that is best.

Research direction
Start by tracing how the live code editor captures and displays compiler warnings, program stdout, and panic stderr. Compare the behavior described for examples 18.1 and 18.2 with 4 and 5.1; done means program output, compiler warnings, and panic errors can be displayed together.
