HTML5 defines the "rules for parsing a list of dimensions" in section
2.4.4.6. Those rules are very close to our legacy code with a couple
of differences:
- For inputs with only leading spaces and a unit, HTML5 return 0 with
the specified unit. The old code would return (1, Relative).
- HTML5 allow doubles for every units and not just percentage.

The 2 new behaviors are more consistent with the author's intent (and
are corner cases) so the compatibility risk of this change is small.
