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 ) {

In `@classes/helpers/FrmAppHelper.php` at line 1381, Update the foreach expression
in the class-splitting logic to normalize preg_split’s array|false result to an
empty array before iteration, eliminating the PossiblyFalseIterator condition
while preserving the existing tokenization behavior.

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.

In `@classes/helpers/FrmAppHelper.php` around lines 1409 - 1410, In the icon-class
handling flow, replace only the first class token by updating $icon_classes[0]
rather than applying str_replace() 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 preserving the existing
$icon replacement behavior.
