When I try to type in a text field with the virtual keyboard, the text field is moved offscreen. Then in order to review your typing you have to put the keyboard away. And if you try to make changes, your selection is cleared and the keyboard comes back up moving the text field out of view. I've attached a video of this interaction.

This is a known issue with the current form manager.

Let's call this a dupe (I expect we're going to gather quite a few of these from nightly testers and unless they are exceptional cases, I think we can just dupe them all.)
