Bug when editing entries or pages with macOS Sequoia - Safari 18

[artprojectgroup]

For some reason the float property is not being applied correctly in the layer with id postbox-container-2. After several tests we have been able to verify that if the property is deactivated and re-activated it does apply it well, so for the moment we have created this temporary code that solves the problem:

<?php
add_action( 'admin_footer', function () {
?>
<script>
jQuery(document).ready(function($){
    $("#postbox-container-2").css('float','none');
    setTimeout(function() { 
        $("#postbox-container-2").css('float','left');
    }, 100);
});
</script>
<?php
} );

We hope that you find the reason why the float property is not applied since we have not found it so far.

By the way, the issue affects the Classic Editor only.

Thank you in advance.

Best regards.
