This is because the integral "sits wrong" in its boundingbox. Almost
all fonts have the glyph centered around the math axis, but there are
a few that doesn't. In euler-math.lfg, add the tweak

{
tweak = "fixoldschool",
},

In fact, we have not updated the euler goodie file for a while it
seems. I think there are more things that can be improved. Hopefully
before next release.

It can also be mentioned that some fonts (Daniel Flipo was quick to
fix concrete, erewhon and kpfonts) was fixed recently regarding this,
and it is reported on and fixed in development of Lucida.
