Summary
Ensured scrolling always succeeds. ScrollingSynchronizer API is changed to support this contract. In IJ, scrolling events are sent frequently,
so the Markdown preview picks only last ones within a certain timeframe. If
scrollToLinefails (because the target block is unsupported, for example), then the scrolling stops abruptly.Ensured scrolling to the block on the first line works.
