Workaround the datepicker appearing below the add_days modal on Safari
requested to merge codeurs-en-liberte/framadate:workaround-datepicker-below-modal-safari into develop
The correct solution would probably be to upgrade the version of bootstrap and bootstrap-datepicker that we use
My understandng of the bug is:
- bootstrap-datepicker finds the first ancestor whose z-index isn’t auto, and sets its own z-index to the found elemenents z-index + 10.
- On Firefox and Chrome, the modal element is returned (its z-index is 1050)
- On Safari, the modal-dialog element is found. Its z-index is auto, but Safari reports this as '0', which makes the z-index of the datepicker 10.
