We have added a workaround fix for the issue. The problem is the need of "composable importmaps", aka an importmap depending on a package that has its own importmap. The workaround involves in copying the dependencies defined in the api importmap into the sample importmap. This can easily be fixed once things are published to JSR, as there is a dependency patching mechanism.
