[cssom][css-logical-props] Resolved value of logical properties

[upsuper]

There is a list in CSSOM spec about properties which should return used value instead of computed value for declaration from getComputedStyle.

The question is, whether their corresponding logical properties should return used value as well? e.g. width should return used value, but should inline-size and block-size return used value?

My understanding is that, the list exists purely for historical reason, so we don't want to add any new property into that list, and consequently the new logical properties should not be put there either.

If that is the case, I think it's worth at least a note in the CSSOM spec that "any other property" includes the corresponding logical properties from CSS Logical Properties spec.

I would actually lean towards having the same behavior for logical and physical equivalents. They are in a weird way aliases to the same property.

I tend agree with @fantasai. It also seems somewhat easier for developers to adopt logical properties if they behave the same as physical here.

In Gecko blockSize returns the empty string. WebKit and Chromium don't implement block-size.

Right, Gecko hasn't implemented that for logical properties (which is unfortunate), and I hope it could get clear before we start implementing it.

Actually I'm fine either way. I just think the spec should make it clear.
