Poll dialog inputs get cut off on mobile

The width of the inputs has been fixed here

UX: minor tweaks to poll builder UI

Opened a separate issue here for the dropdowns being cut-off.

Doesn’t happen in Safari, Chrome, or Firefox on Desktop, so it seems like a bug in iOS with how position: fixed; is handled… [Screen Shot 2020-02-17 at 10.13.28 AM]
