7dc8b68092 Improve horizontal spacing of fractions
A fraction is surrounded by a box of width \nulldelimiterspace on either side.
That size is 1.2pt and does not scale with the style or font size.
Furthermore, a \frac creates a brace-enclosed group which results in a
\mathord, not a \mathinner.

39f5bcb042 Add support for \phantom
Summary:
Using \phantom with non-phantom math in Perseus doesn't render to be the
same size because \phantom uses MathJax and the non-phantom math uses KaTeX.
Implementing \phantom in KaTeX should solve this alignment issue.

Test Plan:
[x] write (and run) unit tests
[x] create (and run) screenshotter tests
