Can't fold a class/method when a range of PHP tags overlaps a range of class/method body

Hi i have a problem with code folding "<?php ?>"

if you have this PHP code

Segnaposto codice // 
<?php
class A {
    function B(){
        ?><div>Hello</div><?php
    }
}

when you create it it's ok, but if you save, close and re-open it ,

you can see collapse <?php -> ?> and break folding as in image (tmp_code_php.jpg)

Actual result after save, close & reopen file .php

image attached wrong_tmp_code_php.jpg

Expected result:

image attached aspected_tmp_code_php.jpg

Thank you
