Fix a too strict check

[Jako]

$page contains an integer and $i contains a float during my tests

What does it do?

Switch to a less restrictive check. In my case the value of $page is an integer and the value of $i is a float. For whatever reason this check was invalid only when the $page is 15 on PHP 8.3.20.

Why is it needed?

To display the active page on page 15 too.
