You mean, if the message to be displayed in the minibuffer uses large
fonts or includes tall images?  In that case, we will simply display
the single line with partially-visible text/image (assuming
max-mini-window-height doesn't allow to resize to see all of it), and
I don't see what can be done about that.

It is highly unusual for messages to use such faces or images, and if
some features do that, users of those features should be told to not
limit the mini-window height to a size that's too small.

Unless we can come up with a change that is either simple or safe.  Or
if we decide that the current situation is so unacceptable that we are
willing to take higher risks of releasing a less stable Emacs 27.2.

I cannot help you with your doubts more than I already did.  If you
still have those doubts, I'd appreciate if you keep them to yourself,
because having them written here is an insult I don't think I deserve.
