--- Comment #2 from Frédéric Wang <fred.wang at free.fr>  2014-02-20 23:55:30 PST ---
I just checked again and actually I think my first comment was wrong. The problem is that mathml.css has some CSS rules to emulate italic correction:

mi {
    -webkit-padding-end: 0.1em;
}
msub > mi:first-child, msubsup > mi:first-child {
    -webkit-padding-end: 0;
}
msubsup > mi:first-child + * + * {
    -webkit-margin-start: 0.14em; /* This is larger than 0.1em because the child's font-size is smaller than the <msubsup>'s. */
}

but these rules should only apply when mi is italic and probably for other italic token elements too. So it's probably best to wait we can do proper implementation of italic correction in the renderer code.
