Regression between preview and cdn - can not be set

For cdn version we can do

        const engine = new BABYLON.Engine(canvasElement, true, { preserveDrawingBuffer: true, stencil: true }); = "Unique Name For the Spec";
        return engine;

The same code for preview version returns

TypeError: Cannot set property name of #<e> which has only a getter

The issue is the name can not be set. Is this intended? Should I report a github issue for this?

on it :slight_smile: We will fix that for next release

Thank you. That was fast.

When is the next release? (just curious for the release)

There should be one later today.
