Title:
UITableViewCell frame is misaligned after beginUpdates/endUpdates while editing

Description:
Auto-sizing UITableViewCell frame is misaligned if you put a UITextField inside one of the cells, make this text field a first responder, then call beginUpdates()/endUpdates() on a table view and then scroll away from this cell/scroll back.

We use beginUpdates()/endUpdates() to update the height of the cell without reloading the row, because it is essential to keep the keyboard on screen.

Steps to reproduce:
1. Create a few auto-sizing cells
2. Put UITextField into one of them
3. Launch the app
3. Tap on that text field
4. Call beginUpdates() + endUpdates() on that table view
5. Keep the keyboard on-screen.
6. Scroll away, so that the text field cell is not visible any longer.
7. Scroll back

Expected result:
UITableViewCell is placed where it was.

Actual result:
UITableViewCell frame is incorrect (much lower than it should be)
