Reproduction on Safari, cannot scroll.

Dropdown menus in the Products view of the web-platform-tests dashboard website cannot be scrolled on Safari. The same menus can be scrolled on Firefox and Chrome. Please refer to the attached screen recording for a reproduction.

The dropdown menu has a CSS attribute `--paper-input-container-input_-_overflow: hidden` which seems a little suspect, but my interpretation says we _shouldn't_ be scrolling on this menu in that case.
