[css-text] The computed value and animation type of tab-size

[upsuper]

The current spec says the computed value of tab-size is "the specified integer or length made absolute", however the animation type is "length".

It seems to me animation is based on computed value, which means either <integer> value is not interpolatable, or <integer> should be converted into <length> when it becomes computed value.

[upsuper]

I'm pretty sure we don't want to convert <integer> into <length> for computed value, because that would affects inheritance. It means <integer> is not interpolatable... which the spec should probably say explicitly.

This was actually reported in https://www.w3.org/mid/20151022224025.GA28022@pescadero.dbaron.org and was resolved in https://www.w3.org/mid/CADhPm3u95z0_xB8eRsmv=EGgb8+8yXDEnw-EAVp3eqrGjs9ykQ@mail.gmail.com and should now be fixed. :)

Since PR26981 has been approved and merged, I am removing the Needs Testcase (WPT) label. Leaving the Needs Testcase (WPT) label as is would only contribute to confusion and loss of time.
