Del key, after emptying a comment line, then imbalances the next form

[pbwolf]

Starting with the document-and-selection

|;•(foo)

(where • signifies a newline), 3 invocations of deleteForward produce the following series of documents

|•(foo)
|(foo)
|foo)

The last one, the form's open-paren having been deleted, is unexpected. I expected

(|foo)

The "calva:cursorInComment" context remains in effect even after the Delete key removes the last vestiges of a comment, and therefore(?) the niceties of paredit do not apply to whatever happens next.
