Some properties are just ignored

[SebastianStehle]

Prerequisites

• Can you reproduce the problem in a MWE?
• Are you running the latest version of AngleSharp.Css?
• Did you check the FAQs to see if that helps you?
• Are you reporting to the correct repository? (there are multiple AngleSharp libraries, e.g., AngleSharp.Xml for Xml support)
• Did you perform a search in the issues?

Description

I have realized in another scenario that some properties are just ignored. I have created a PR for that: devel...SebastianStehle:AngleSharp.Css:devel

I copied an existing test and changed the property for that.

Steps to Reproduce

See: devel...SebastianStehle:AngleSharp.Css:devel

Expected Behavior

All properties should work (even if not correct)

Actual Behavior

Some properties seems to be ignored.

Possible Solution / Known Workarounds

I have no idea. I have narrowed it down to here:

AngleSharp.Css/src/AngleSharp.Css/Dom/Internal/CssStyleDeclaration.cs

Line 289 in 459b48c

if (property.RawValue is not null)

In this case value is correct but RawValue is null and I have no idea why.
