Expected behavior

The keyboard should appear and stay.

Actual behavior

The keyboard appears, then disappears, endlessly.

Steps to reproduce the behavior

1. Create new post
2. Type title
3. Double-tap below the title to enter text.

I could only reproduce it when making a new post, not when editing that post after saving it once or editing an existing post.
