Wrong "Editor selection is not within a code cell that supports formatting."

[mcanouil]

Bug description

This is mostly to track real impact of this.

In some cases (unclear what are the requirements here), even though the document is correct and there is a valid code cell, the extension displays an error notification: "Editor selection is not within a code cell that supports formatting."
