I went ahead and looked into this myself.  Looks like the issue is that the properties (lprops) are set using symbol properties with org-agenda-redo-command, which is buffer-local.  However, according to the elisp manual (at least for the upcoming 26.1 release), symbol properties aren't buffer-local; only the value itself is.  Thus, lprops are overridden by a new agenda.

I've created the following patch to address this.  The symbol property is used as a temporary variable, but the actual lprops are stored as a buffer-local variable to each agenda buffer.
