Pinegrow live does not 'show' 'offcanvas' elements in the editor when 'show' is applied as a class

Description: Bootstrap 5 ‘offcanvas’ javascript components function correctly in browsers and are visible in the Pinegrow app, but not in Pinegrow live.
Steps to repeat: Apply the offcanvas, offcanvas-start, and show classes to an element with content and note how the component does not appear in the Pinegrow Live version, but does in the Pinegrow App.

I have just realised that all this time I was running with JS off in the live version, and JS on for the app version. This can be closed.
