After a long session of debugging, I have come to find that iOS 10 places a maximum height of 2047 on its UITableViewCell; any value higher than that causes the UITableView to render incorrectly or to behave strangely (e.g. not scrolling anymore). This behavior cannot be reproduced in iOS 9, where the same code runs without a hitch.
Is this intentional, and if so, what could be done?
