I'm seeing this as well, seems to my it's anytime I put .0 into a cell it freezes that cell.

Something related

When I put my cursor after 5, I cannot delete the 5 with backspace.

I can reproduce the behaviors reported by both OP and me on juypter notebook, so jupyterlab is not involved.

See #929 and codemirror/codemirror5#6288. This comes up a lot and is actually an upstream issue (with the CodeMirror project, not with IJulia).

The short description of the issue is that it goes into an infinite loop while trying to parse the syntax to do highlighting.

codemirror/codemirror5#6288 (comment) says it should be a jupyter / jupyterlab issue. Is this true? If so, jupyter / jupyterlab team should be notified.

[twavv]

They know.

jupyter/notebook#5469

[atbug]

Seems to be fixed on jupyterlab 2.2.6.
