Add missing unitless CSS properties

[kripod]

What: Similarly to the pull requests I made towards React and Preact, I'm adding all the missing standard and experimental unitless CSS properties, collected from MDN data.

Why: To postfix all the numeric values passed to unitless CSS properties with 'px'.

How: With thorough testing, as described in the related Preact issue.

Thank you for this! I'd like to see what happens with the React PR before we merge this here - although I don't expect any objections to this coming from the React team.

[kripod]

After the discussion on the React issue, I decided to close that PR, due to the reasons outlined over there. I even opened a new issue for otion, so that once we may all migrate to a more sustainable approach.

[Andarist]

What do you think should happen with this PR here then?

[kripod]

I think this should be closed for now, until the React team decides upon a better solution.

[kripod]

My PR towards Preact has been accepted, so we may want to re-evaluate the value of this fix.

[Andarist]

I must say that in the end, I feel very similar as React team. Maintaining a whitelist is just troublesome - there was also no actual user request about those being missing. If that's OK with you - I would like to decline this for now.

[kripod]

That’s totally reasonable, thank you for answering!
