Unable to scroll to the bottom of a post after adding a list

[frosty]

When I add a list to a new post, the scroll + content insets of the editor are incorrect, such that the bottom couple of lines of text aren't visible and I can't scroll to them:

I'm seeing this behaviour in both Aztec Example and WPiOS.

Steps to reproduce:

• In the example app, go to the Empty Editor.
• Add multiple lines of text (can just be one word per line) so that the post scrolls
• Add a list – it can be at the bottom or further up
• Notice you now can't scroll to the end of the post
