Description Henning 2023-03-14 10:03:36 UTC 
SUMMARY
At the moment the Preview plugin is not really usable


STEPS TO REPRODUCE
1. Create a md document longer than one page
2. Write something, enable auto reload in the preview plugin
3. try to scroll down in the preview and edit the document

OBSERVED RESULT
The preview plugin blinks constantly, which is horrible (epileptic typiiiing)
Also when you edit something, it skips to the first page. When I delete that text again, it skips to where I was again, really weird.

EXPECTED RESULT
Somehow load the diff instead of the whole document, or maybe load invisible and only make the new document visible when when its loaded, blending the old and the new one together, instead of OLD->nothing->NEW (blinking)

Skip to the current page on the preview.

The preview plugin is not maintained, if you want to have this improved, please
submit a merge request, otherwise that will stay the way it is at the moment.

I am sorry that does create issues for you, but the only other fix would be to remove it.
