I tested this with the latest Mojarra and you are correct. Abandoning a
flow while simultaneously entering another flow is not allowed.
Currently you have to visit the unbounded flow first and then enter the
new flow.

I have opened spec issue 1253 on this and also ask for more feedback
here if people think this should really be supported.
