Blockquote Rendering and Export Differences

Blockquote markdown is handled differently depending on how an object is accessed.

Some examples:

MCP output:

"A system of assigning value..." — Talila A. Lewis, January 2022 update

Markdown export:

"A system of assigning value..."

— Talila A. Lewis, January 2022 update

And it's different in app/web rendering. (See attached screenshot.)
