splitting cell results in incorrect cell language

[jonsequitur]

Steps to repro:

• Create a notebook with the default kernel of F#
• Create a cell and set the cell language to JavaScript
• Enter the following code into the cell:

  x = 1;
  console.log(x++);
  

• Put the cursor at the end of the first line.
• Trigger command Notebook: Split cell

Expected:

• Two cells, both JavaScript

Actual:

• Two cells, the first is JavaScript and the second is F#.

Seems like a related issue to this has been closed perhaps by changes on the VS Code side. Does that mean this is addressed as well?

This issue is still present.
