Unclear runtime behaviour of Python code in CQ-Editor for subsequent runs

I have just installed CQ-Editor master via

conda create -n cqgui -c cadquery -c conda-forge cq-editor=master python=3.7
conda activate cqgui

and added MAssembly on top:

pip install git+https://github.com/bernhard-42/cadquery-massembly

You might remember, MAssembly is a subclass of cq.assembly.Assembly, see here

I now run a little test program more than once:

import cadquery as cq
from cadquery_massembly import MAssembly
import logging
import time

a = MAssembly()
logging.info("At %s, result %s", int(time.time()),  isinstance(a, cq.Assembly))

Pressing the green “Run” button three times I get:

So from the Log Viewer, the first time CQ-Editor recognises a as being an object of class cq.Assembly. For all subsequent runs not.

What am I doing wrong here?

Btw., this prevents from using MAssembly in CQ-Editor now, since cq.assembly.Assembly.add() will now run into an infinite python recursion.

fyi, MAssembly is now working perfectly in CQ-Editor

yep indeed, it works now. Thanks! Maybe it would be an idea to have the default for this preference changed? Because it is a little bit unexpected …
