[css-values-5] should 'calc-size(0)' work? #10354
Description
In https://issues.chromium.org/341564374 @yisibl pointed out that calc-size(0) doesn't work. I think this matches the current spec which defines the behavior to work like calc(), where it was intentional that calc(0) doesn't work.
I think despite the parallels with calc() we may want to consider making calc-size(0) work correctly, because:
calc-size()is explicitly for lengths only so there's less concern about unit algebra making sense- it would be nice to preserve the principle that "wrap an animation endpoint in
calc-size()" works in general, and0is one of the most common length animation endpoints.
