Commit [1] was not coded defensively enough: after it, dialogs not using
a proper bootstrap structure triggered a traceback once they were opened
(this was discovered on odoo.com where such unconventional dialogs do
exist). Bad luck: there was actually a check to allow unconventional
dialogs but it was not done at the right location.
However, fixing this, it was found that more than this was not ok. There
is actually no need to consider the modal-content element at all. Just
using our `hasScrollableContent` method is enough and requires no extra
search in the DOM. This actually also properly computes if the modal
overflows or not while it was not the case before as it did not consider
the modal-dialog element's paddings.
Finally, the whole customized behavior of the modal scrollbar here was
only designed to affect our Odoo modals with the s_popup_no_backdrop
class (see original commit [2]). Indeed, only in that case we want to be
able to switch between body scrolling and modal scrolling while the
modal is opened. In custom cases and other Odoo cases, we want the
standard Boostrap behavior of only being able to interact with the modal
while opened. This commit cleans the code to restore that spirit
(hopefully this does not cause stability issues as [1] was introduced
only a week ago). Sorry for any inconvenience.
