When executing later code cells, the execution counter is increased, so clearly the kernel receives and executes the eval request, but for some reason does not reply with the result.
Description
I have installed jupyterlab-myst in my own JupyterLite deployment (https://lab.climet.eu/main). The frontend-only functionality works, e.g. I can render extra Markdown as expected. jupyterlab-myst also offers in-Markdown evaluation using the
syntax which calls into the running kernel. In JupyterLite, this does not seem to work. Instead of displaying
3, it shows1+2. In the debug console log, I can see that communication with the kernel occurs:When executing later code cells, the execution counter is increased, so clearly the kernel receives and executes the eval request, but for some reason does not reply with the result.
