 I have block themes that define layout ({{{contentSize}}} and
 {{{wideSize}}} in {{{theme.json}}}) using {{{min()}}}

 The issue is that {{{wp_get_layout_style()}}} returns nothing as
 {{{safecss_filter_attr()}}} does not recognize {{{min()}}} as valid CSS.

 This was not previously an issue because it used to be filtered using
 {{{wp_strip_all_tags()}}} as {{{gutenberg_get_layout_style()}}} still does
 when Gutenberg is active.

 However there is a TODO note in Gutenberg that it will switch to using
 {{{safecss_filter_attr}}} in future.

 I would ask that {{{min()}}} and any other missing valid CSS be allowed
 similar to how this was fixed to allow {{{calc()}}} and {{{var()}}}
