[pmwiki-users] anchor in url prevents editing

[JB]

Having an anchor in a url makes "?action=edit" stop working.

For example at url:

   http://gnuzoo.org/test/AdvancedTableDirectives#zebratables

try to edit via URL:

   http://gnuzoo.org/test/AdvancedTableDirectives#zebratables?action=edit

It does not go to the editor. Is there a way to fix this?
