When using julia in jupyter lab. the completion function sometimes does not work. For example, when I press the tab key after \pi, it is not converted to the Greek letter π, but to a space. Is there a cause for this?

- jupyterlab: ver. 3.2.9
- julia: ver. 1.8.5, 1.9.3

Probably handled by IJulia, so perhaps worth opening [an issue](https://github.com/JuliaLang/IJulia.jl/issues) there about this.
