It can legitimately happen if the bold font is either slightly higher
that the default font, or the line displayed by eldoc is longer than a
single screen line.

This is not a bug, even if it still can be reproduced.

However, the OP didn't say what was on line 902 of abbrev.el in that
version of Emacs, so it is impossible to find out what actually
happened.
