Be in Right to left
Open a m2o search more, to get onto the list modal
toggle the filters menu
Before this commit, the filters dropdown was almost invisble
and too much on the right anyway
This was because the RTL was not taken into account
After this commit, we anchor the dropdown on the right
(both as in good and as in side) side of its trigger button
Also, when modifying the dropdown, by developping the Custom Filter
we force the repositioning of the dropdown, to take those new elements
into account
It is expected though that after this commit, in RTL, the
dropdown in a modal that has a scrollbar (which is on the left)
will be slightly pushed to the right. It is usable and visible though
Some kind of plumbing using $el.data('offset', fn) from popper.js
is possible, but has been deemed not robust enough
