With 'mru' the window used by 'display-buffer-use-some-window'
is the last one.  Here is the use case of the OP:

    When cycling through, say, a rgrep result buffer with n
    (next-error-no-select) and p (previous-error-no-select), file results
    are displayed in every open window, with the exception of the window
    containing the rgrep results themselves.
    I'd rather have file results remain in just one window
    so that I can use other buffers while still viewing search results.

Unfortunately, a side window is not a solution since after finishing
navigating the search results, the window should remain normal.
