Thanks for the bug report.

Yup, there is no particular behavior associated with `show'.
Valid choices here include nil, t, `jump', and `jump-offscreen', and
while the last one will move the cursor off screen, t and jump will only
show the position in the echo area.
I have now fixed this on master (commit b2c50d7cf3) with the below
patch. This change will be a part of the upcoming Emacs 28.1.
