Just because delayed-warnings-list is ordered last-to-first and it's
easier to find the last one that the first one.

But this assumes that all such display warnings are produced by calls
to warn_about_display_error, and so they are all

  Error (display): Please check *Messages*

If we want to allow different kinds of display warnings, then the
thing to do is not to display the first one, but accumulate and
display them all (duplicates are no problem anyway because they are
collapsed by collapse-display-warnings, which runs before
show-display-errors-when-idle).
