Parsing border width specified as negative zero #44

Closed hrj closed 8 years ago

hrj commented 8 years ago

There are about 32 tests which depend on this:

border-bottom-width: -0ex;

The above should be parsed as valid CSS and hence appear in the node data. Currently it is parsed as invalid, which effectively means the property gets the value "initial" which then computes to non-zero in some circumstances.

Variations of this test include: -0em, -0in, -0mm, -0cm, -0pc, -0pt, -0px.

I guess this also applies to all length specifications: margin, padding, etc. But haven't found their corresponding tests.
