To make the magnification debugging easier, we add the dump information
for magnification tracking typing focus feature.
For full screen magnification, it includes
MagnificationFollowTypingEnabled.
For window magnification, it includes both
MagnificationFollowTypingEnabled and TrackingTypingFocusEnabled.
MagnificationFollowTypingEnabled is controlled by system preference
setting.
TrackingTypingFocusEnabled is controlled by a user behavior.
