Add Backdrop Blur to Mask

It would be great to add a backdrop filter to the mask component. Right now, I have tried different ways to edit the mask but I can't add a backdrop filter

Start by locating the mask component and reviewing how its current styles are applied. Confirm how backdrop filtering can be supported there, then verify visually that the mask applies the requested backdrop blur without breaking existing behavior.
