For context, I primarily have cards that have long texts with clozes. This bug relates to those types of cards.

###### Reproduction Steps

1. Open a deck's cards for study
2. Scroll down until I find the cloze "[...]"
3. Tap "Show Answer"

###### Expected Result

The page view stays where it is - no movement.

###### Actual Result

The page view jumps all the way back to the top of the screen. I have to scroll down again, to find the now-revealed answer.
