I did run into an issue though. By default, events handled by Lil Brother don't bubble up. The documentation doesn't mention that the
bubblekeyword needs to be set to
truefor the event to bubble up. Otherwise, the
bubbleargument is undefined which causes the event propagation to stop.
I couldn't figure out how to upload new documentation to github, so I forked the project and updated the documentation. Hopefully this will save someone else a couple of hours debugging. :-)
