scale9Grid on clips imported from swf assets

I defined and imported a MovieClip from a swf. This MovieClip has a scale9Grid defined in Adobe Animate, but it’s not defined after importing in an HTML project. Should this be expected to work? Thanks.

Upon looking deeper, it seems scale9Grid isn’t supported in html5 (or is it?)

scale9Grid is only partially supported, but I want to see it stable before the OpenFL 9 release :slight_smile:
