[mathml] Adjust padding for invalid fractions reftests

fred-wang · chromium-wpt-export-bot · commit f6d8412357af · 2021-07-09T07:34:27.000-07:00
The invalid fraction reftests compare an <mfrac> with an invalid number of children against an <mrow> with the same children, in order to test this statement from [1]: "If the <mfrac> element has less or more than two in-flow children, its layout algorithm is the same as the <mrow> element." However, the same section indicates just above a default padding for mfrac elements, so the reftests can't match. This CL fixes that by making the reference set these padding values to 1px.
