Description

It's been a while since the list of CSS properties in CSSDefinition.php has been updated. There are many new properties available with CSS3, many of which have become standardized. I think it would be a good idea to update the basic doSetup info method with all the safe standardized CSS3 properties.

I would gladly commit the changes.

Research direction

Start in CSSDefinition.php and inspect the doSetup method, then identify which standardized CSS3 properties are considered safe for inclusion. Update the property list there and verify that the resulting definitions cover the intended safe properties without broadening the filter unexpectedly.
