Before this commit, when a dropdown overflew its container
i.e. in the case of a long filter menu in modal
The scrolling of that dropdown to get to Add custom Filter
was impossible
This was because dropdowns react pretty bad when contained in a
relative positioned container
https://github.com/twbs/bootstrap/issues/26512
https://github.com/twbs/bootstrap/issues/28513 !!
After this commit, the btn-group that adds the relative positioning
is forced into the default value
This commit corrects what was initially
corrected at https://github.com/odoo/odoo/pull/37594
in v12.0.
The incriminating commit that retriggers the issue
is irrelevant because it is the refactoring of action manager
but here it is: 40dd121938
