Description
This is more of a new use case than a bug, but it should probably work. Seems like quite a good opportunity to improve map usability.
When you create a map using the following markup and then you change the projection="OSMTILE", via $0.projection = "CBMTILE", the layer should continue to be displayed, with the different content from the CBMTILE extent. It doesn't throw errors, but it doesn't work.
<!doctype html>

<!-- the layer in this map should continue to be visible when you change
the viewer projection from OSMTILE to CBMTILE. -->
