Before this commit, users wasn't able to scroll vertically when there was "table-responsive" class on modal's table. In fact the scroll was effective on the body and not in the modal content. We can fix this issue by having flex elements but as this is a fix, we preferred to choose a one line fix solution. Steps to reproduce : * open Odoo in Safari (iOS) * open Sale app * create a new quotation * select a customer * select "Search More ..." * try to scroll the table vertically (BUG) Sources : https://stackoverflow.com/questions/41681251/overflow-x-scroll-inside-a-fixed-div-prevents-vertical-scrolling-on-ios#comment84970666_41693350 https://stackoverflow.com/a/57566116 opw-2042095 closes odoo/odoo#36707 closes odoo/odoo#36730 Signed-off-by: Adrien Dieudonné (adr) <adr@odoo.com> Signed-off-by: Adrien Dieudonné (adr) <adr@odoo.com>
