"Insert Chunk" keyboard shortcut not splitting chunks in Quarto notebook when line in existing chunk is selected

Steps to reproduce the issue:

In RStudio notebooks, if you press command + option + I when a line outside of a chunk is selected, a chunk is inserted. Pressing the same when a line in the middle of a chunk is selected, it splits the chunk into two chunks at the selected line.

In Positron notebooks, pressing command + shift + I will select the line under the chunk, insert a new line and then insert a new chunk.

I'm assuming this was not intentional because I couldn't find a "split chunk" shortcut, but I'm happy to be corrected here.

What did you expect to happen?

I expected Positron to split the chunk when using the insert chunk shortcut when a line in a chunk is selected.

Were there any error messages in the output or Developer Tools console?
No.

This behavior is from the Quarto VS Code extension, and I logged the issue here: quarto-dev/quarto#382
