When the first image is generated, the autoscroll triggers before the image is fully displayed by the browser. This causes it to not be positioned properly.
The fix is to listen for the "load" event on the IMG element before triggering the scrolling event. Once the image fully loaded and rendered, the browser correctly detects the size of the viewport and renders properly.
After thinking about it, the auto-save toggle is meant for the *Editor* fields listed behind the Configure button. The auto-scroll toggle is not part of the Editor, and is more akin to a system setting, although it's placed in the main UI for convenience reasons related to its nature. As such, and especially considering it's a plugin, I lean towards decoupling auto-scroll from the auto-save settings, and just storing it independently.
