Can't use result of is_numeric to determine ability to cast

Bug report

I would have expected no errors in the code snippet below. If a $var is numeric I should be able to cast it to int, but it doesn't seem that phpstan recognizes this.

It works with is_scalar though.

Expected output

No errors
