Document Preview doesn't scroll to the top with Scroll Sync

When opening Dillinger, the preview for the default document is already scrolled down a few lines. No matter how many times I turn the Scroll Sync on and off, the preview never scrolls all the way to the top when I scroll the markdown up. It happens with all the documents I tested. Scrolling the preview directly works as expected.

If I scroll the preview all the way to the top and switch to the markup side, as soon as I scroll down even slightly, the preview jumps to the same place it will go back up to later, around 160-180px from the top of the preview.
