When that happens, do you see any message in *Messages* besides the
one displayed in the echo area?

In general, a single-line message should not resize the echo area.  If
the echo area is resized, then recentering you describe is a normal
reaction of the display engine.  So the question now is why the echo
area is enlarged to 2 lines.
