1820875 - NaN and infinity times are not serialized or parsed correctly

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect)

Description

[Oliver Medhurst [:canadahonk]]

Times like NaN and infinity (and -infinity) should be serialized properly as per spec, see WPT tests for examples. Additionally, they are not parsed due to some parse-time clamping internal limitations with time values.

Attachment: Bug 1820875 - Parse and serialize NaN and infinity times correctly

Times like NaN and infinity are now parsed and serialized correctly.

Also added a new WPT test to cover a missing edge case:
calc(1<unit> * NaN) -> calc(NaN * 1<canonical_unit>)

The very similar angle tests do this already for angle's units.
