When there's a comment at the beginning of a form:

;; x
(= 5 4)

If you start from the start of the first line and select forward with control+shift+rightarrow (Calva Paredit: Select Forward Sexp), it seems like it doesn't do paredit selection. After 5 Select Forward Sexp, the cursor is between the 4 and ).

This is with Ubuntu Linux 24.04, VSCode: 1.100.2, Calva 2.0.520.
