When accessing a card on Safari on an iPhone, the 'Share' button remains hidden.

Issue Summary

When users open a card through Safari on their iPhones (not through the Trello app), the 'Share' button of the card stays hidden, and the user doesn't have the option to select it.

Steps to Reproduce

1. Open your Trello board on Safari
2. Then, open one of your cards
3. Scroll down the page while on the card's back
4. You'll notice you can't scroll down further, which prevents the user from selecting the 'Share' button.

Expected Results

Users accessing cards through Safari should be able to access the 'Share' button when scrolling down the page when viewing their cards on Safari. 

Actual Results

Viewing the cards back on Safari doesn't allow users to select 'Share' since they can't scroll down further. 

Workaround

Users can zoom out the screen on Safari to 50% or use a different browser, such as Mozilla Firefox or Chrome, and they won't experience this issue when navigating on the card's back to access the 'Share' button. This issue also isn't present when viewing a card on Safari through an iPad.
