Only passed when there is content assigned by the content property.
This list is for properties that need to be propagated to the generated DOM
element as browser CSS properties. Keep browser-expanded longhands here
rather than their shorthand forms (for example, text-box-trim/text-box-edge
instead of text-box).
text-autospace and text-spacing-trim are intentionally omitted for now:
generated content handles them via TextPolyfill.processGeneratedContent()
with explicit values from boxInstance.getProp(), not by inheriting browser
CSS properties. If generated content switches to browser-native handling for
those properties in the future, add them back here.
