Research direction
No files, tests, or entry points are named. Start by reproducing the sample code in JupyterLab with the listed streamz and Jupyter versions, then compare the same cells in a Jupyter notebook; done means each cell displays its own output consistently.

Description
I just discovered steamz and think it looks great. However, when I try to run some of the sample code in a Jupyterlab notebook, I experience some strange behavior where the I sometimes get output of "Output()" and then, when running a subsequent cell, get the output of the previous cell. This only happens in Jupyterlab not a Jupyter notebook.

Here are some package versions installed:
anaconda-client==1.7.2
anaconda-navigator==1.9.7
anaconda-project==0.8.3
dask==2.5.2
dask-labextension==1.1.0
ipywidgets==7.5.1
jupyter==1.0.0
jupyter-client==6.0.0
jupyter-console==6.0.0
jupyter-core==4.6.3
jupyter-server-proxy==1.2.0
jupyterlab==2.0.0
jupyterlab-server==1.0.6
nbconvert==5.6.0
nbformat==4.4.0
notebook==6.0.3
streamz==0.5.2
toolz==0.10.0
tornado==6.0.3
widgetsnbextension==3.5.1
Any thoughts?
(I also had the same behavior using the docker container PR)
