Trying to run my fledgling Robot Framework project (which runs fine under both Robot 4.1.3 and pabot) and noticed a wierd failure when running under xeus-robot / JupyterLab.
On my Ubuntu 20 Linux box, under miniforge, installed as follows in a clean env:

conda install xeus-robot voila jupyterlab

Then:

jupyter lab --no-browser --ip=0.0.0.0

I am accessing JupyterLab from my Windows box via Edge / Chrome and it works great.

I pared down the failing case to creating a small file dictionarybug.robot with the following content:

*** Settings ***
Documentation	Reproduces dictionary bug with xeus-robot.

*** Variables ***
&{CONNECTIONS}	1=IxServerTest	4=UartTest	23=FprogTest	48=TECProxyTest	119=IxIoTest	129=L23Test	208=PGIDIxAccumulatorTest

Then, from a blank JupyterLab Robot notebook I run the following:

*** Settings ***
Documentation	Reproduces a bug with xeus - Robot Framework.
Resource	${EXECDIR}${/}dictionarybug.robot

*** Tasks ***
Repro
  Log Variables

It will show:

---------------------------------------------------------------------------
TestSuiteError:

Invalid dictionary variable item '{'1': 'IxServerTest', '4': 'UartTest', '23': 'FprogTest', '48': 'TECProxyTest', '119': 'IxIoTest', '129': 'L23Test', '208': 'PGIDIxAccumulatorTest'}'. Items must use 'name=value' syntax or be dictionary variables themselves.

Oddly enough, if I comment out the line containing the dictionary, and run, it will of course run without failure; but then if I uncomment the line and run again, it will work exactly once (and the dictionary will appear in the log).
Then, if I run again, it will fail miserably.
