Comments URL renders incorrectly in Panels Page

I have a single Panels2 page with an embedded "Node" context and a "User from Node" relationship.

The panel page is successfully pulling in the node body (node/1576) and the related node author "About" profile and the appropriate related node comments in separate panels. Perfect!

However, the links rendered in the comments panel are incorrect when displayed as "threaded-collapsed". Instead of being rendered, for example, as -- http://server/node/1576#comment-678 -- they are instead rendered as -- http://server/%252F678#comment-678 --

In other words, Panels2 seems to be exhibiting the following problems:

1. Retaining the panels page URL instead of replacing with the node URL
2. Encoding problem: "%252F" instead of "/"
3. Repeating the c.cid before the "#comment-"

When displayed in a panel as "threaded-expanded", however, the comments and their associated links are rendered correctly.

Thank you for any assistance you can provide.
