This changeset adjusts the logic to use a more defensive approach, to avoid passing potentially invalid values to `wp_add_inline_style()`. Props flixos90, mukesh27, costdev, swissspidy, poena, sabernhardt. Fixes #57777. Built from https://develop.svn.wordpress.org/trunk@55427 git-svn-id: http://core.svn.wordpress.org/trunk@54960 1a063a9b-81f0-0310-95a4-ce76da25c4cd
