Bootstrap modal, modal-body with overflow, popover pops under header or foorter. Any workaround? - bootstrap-modal

Question

I'm looking for a proper workaround for that bootstrap problem.
When we use the following css hack from some other stack overflow questions to make sure the modal doesn't go higher than the screen and at the same time having a vertical scrollbar for the body. This actually works just fine and is the desired behavior.
.modal-body {
max-height: calc(100vh - 210px);
overflow-y: auto;
}
the popover inside the modal-body pops under the header and/or footer. See the following fiddle for an example : https://jsfiddle.net/2qeo99k3/4/
or the code bellow. I didn't find any answers on this specific problem after searching or clicking questions that may already have my answer. Changing the popover z-index has no effect.
<style>
.modal-body {
max-height: calc(100vh - 210px);
overflow-y: auto;
}
</style>
<script type="text/javascript">
$(document).ready(function () {
$('[data-toggle="popover"]').popover();
});
</script>
<div style="padding:12px">
This example have a popover at the top and one at the bottom. Click them to see that the popup shows under the header or the footer of the modal when using the css for the modal-body

Wow it was fast. After searching even more I found this :
$('[data-toggle="popover"]').popover({ container: 'body' });
It solves the problem
