Nice this is going to be useful for https://github.com/jupyterlab/jupyterlab-plugin-playground 👍

According to jupyterlab/lumino#377 (comment) this was initially not meant to be backported to Lumino 1.x, but I guess this might be related to the recent change of the TypeScript target, or other reasons?

This is exactly the reason I pushed forward.

The backport was requiring some changes that I did not get the time to do what was necessary. And at that time I did not think it would take so long to get 3.6.0 out.
