The last update to Roboto Italic has a stray point in delta.alt with a
y value of -11299. This causes metrics to give too much vertical space
in some cases.
This is a "hot patch" fix, with the stray point deleted using TTX. We
want to fix the font upstream as well, but this should fix things in
the mean time.
