normalize preg_split’s array|false result to an empty array before iteration,
eliminating the PossiblyFalseIterator condition while preserving the existing
tokenization behavior.
- Around line 1409-1410: In the icon-class handling flow, replace only the first

across the entire $class string; then rebuild $class from the token list so
modifier classes such as frm_clone_solid_icon--muted remain unchanged, while

Normalize the preg_split() result before iteration.
preg_split() returns array|false, so this foreach can trigger Psalm's PossiblyFalseIterator error. Use an empty array fallback.
Proposed fix
- foreach ( preg_split( '/\s+/', $class, -1, PREG_SPLIT_NO_EMPTY ) as $single_class ) {
+ $classes = preg_split( '/\s+/', $class, -1, PREG_SPLIT_NO_EMPTY ) ?: array();
+
+ foreach ( $classes as $single_class ) {📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Replace only the icon class token.
$class accepts a whitespace-separated class list. For frm_clone_solid_icon frm_clone_solid_icon--muted, both tokens remain in the rendered output, but both str_replace() calls rewrite the styling token to frm_clone_icon--muted. Update $icon_classes[0], then rebuild the class list.
