backdrop-filter option for the inner Section blocks

It would be nice if for the row layout block when the overlay image is set, it had settings for the backdrop-filter. https://k2.nevetssoftware.com/can-i/ uses CSS to add a backdrop-filter set to blur the overlay image. Having the ability to set this directly in the block would be useful. backdrop-filter: https://developer.mozilla.org/en-US/docs/Web/CSS/backdrop-filter
