SF-3579 Fix lynx autocorrect not working after note embed

[siltomato]

This PR fixes an issue where note embeds were causing lynx lib position calculations to be incorrect, as lynx lib uses the delta from the DB doc, not the editor delta which may contain note embeds.

The fix involves adjusting the offset used by lynx lib, subtracting the number of preceding note embeds.
