Breaking changes

Snapshots may change due to new formatting on the class and style HTML attributes. Run jest -u to update.

The changes are as follows:

• class attributes are now whitespace-normalized (trimmed and single-spaces only)
• style attributes are similarly normalized, with a terminating ; for each individual style. In addition, invalid styles are now omitted (e.g. color: foobar), and property values may be normalized (e.g. color: #FFFFFF becomes color: rgb(255, 255, 255);).

What's Changed

• fix(serializer): normalize class attributes by @nolanlawson in #236
• fix(serializer): normalize style attributes by @jmsjtu in #237
