View multiple emails at the same time with mu4e

I use mu4e to read my emails. I often find myself wanting to see the content of two or three emails at the same time, in different windows in the same frame. However, mu4e doesn’t seem to allow for this.

Specifically, what I’d like to do is:

• from the Headers view, open a message. This will split the frame into two frames, the headers and the individual message view.
• Then, I’d like to see a second email beside the first. I try moving point to the message view, splitting the window vertically, and then selecting the second message from the headers window
• I’d like for one of the two windows showing the first email body to be replaced by the body of the second email
• what happens instead is that the two message windows are both closed, and replaced by a single window showing the body of the second window.

The exact details aren’t crucial here. What I need is a way to simultaneously display the body of two emails at the same time, in different windows in a single Emacs frame. Is this possible?
