It has already been pointed out that this is due to the fact that the
number `1' is taller than the letter `a'. Here is the relevant bit of
the make_fraction routine:
https://github.com/TeX-Live/texlive-source/blob/35f189ca2c2866a9ed817da1db5d0bd165a3ec61/texk/web2c/tex.web#L14624-L14627
The height of the resulting vlist is the height of the numerator plus
the shift to compensate for numerator's depth and the fraction bar.
