Vector graphics with shadows no longer display

Expected Behavior

imported vector graphics with a shadow, previously displayed correctly, with the shadow, in both the editor and the scratch stage (but not in costume thumbnails)

Any edits would remove the shadow (and similar effects such as corner rounding)

Actual Behavior

imported vector graphics with a shadow, will not display on the stage (but will in the editor). As far as I can tell, this is only affected by the shadow property. Corner rounding still follows the previous behaviour.

Steps to Reproduce

Steps to reproduce the behavior:

1. Go to 'https://scratch.mit.edu/create'
2. Click on 'import costume' or 'upload sprite'
3. Import an SVG costume with a shadow effect (try creating one in a tool like Figma)
4. Any element with the shadow effect does not render

See the project: https://scratch.mit.edu/projects/655176140/editor

look at the costumes of the first sprite

Reproduce the issue at https://scratch.mit.edu/create by importing an SVG costume with a shadow, then compare its appearance in the editor and on the scratch stage. Done means imported vector elements with shadow effects render on the stage as they did previously, while costume thumbnails may retain their existing behavior.
