Comment (by aduth):

 At a minimum, I'd expect the `safecss_filter_attr` to include those style
 properties produced by blocks shipped with core. To this end, I've audited
 the save implementations of existing blocks, and discovered the following
 properties:

 - `background-color` (button, cover, paragraph, pullquote)
 - `background-image` (cover)
 - `background-position` (cover)
 - `border-color` (pullquote)
 - `color` (button, paragraph, pullquote)
 - `font-size` (paragraph)
 - `grid-template-columns` (media-text)
 - `height` (spacer)
 - `max-width` (image)
 - `text-align` (heading, paragraph, quote, subhead, verse)
 - `width` (image)

 Cross-referenced against the [https://github.com/WordPress/wordpress-
 develop/blob/5.1.1/src/wp-includes/kses.php#L2070-L2141 default
 `safe_style_css` set], here's what's missing:

 - `background-position`
 - `grid-template-columns`
