Bug report

IE11/iPhone SE/iPhone 5 problem with mobile breakpoints

Tradeshift UI version affected

v9.3.13

Expected Behavior

On iPhone devices on portrait view I would expect to see only one card per row, ts-mobile-only class should be displayed. If I switch to landscape view, I would expect to see either mobile view - one card per row (ts-mobile-only class) or tablet view - two cards per row (ts-tablet-only class), it depends on the resolution.

Actual Behavior

On iPhone devices on portrait view I can see two cards per row that means that ts-tablet-only class is displayed and not ts-mobile-only as I would expect according to the device resolution.
On Android device everything works fine and the breakpoints seem to be correct (as far as we tested until now).

Steps to reproduce

Login on iPhone device.
Access Document Manager app or ui.tradeshift.com and see how the content is displayed.
