Fixes a BC break in how the font-family name is pulled from the incoming font data.
Merge from Gutenberg's PR WordPress/gutenberg#54615.
What?
Gets the font-family name from the
"fontFamily"
field, instead of the"name"
field.Why?
To avoid a back-compatibility (BC) break for themes that do not have the
"name"
field defined.WP Core also does not require the
"name"
setting. Using it exclusively is a BC break.It's not clearly documented that the
"name"
setting is required. Thus, it's been optional.How?
Uses the font-family's
fontFamily
field instead of itsname
field.As the
fontFamily
field could be a comma-separated list of font-families, it parses the list to extract the first entry.Why
fontFamily
setting?WP_Theme_JSON
schema requires thefontFamily
setting in each of thetypography.fontFamilies
