Docs-preview: Side-by-side markdown code and preview erratically jumps around when editing code #878

Open dime10 opened 3 years ago

dime10 commented 3 years ago

Issue Type: Bug

  1. Open a markdown file with some content longer than the window height.

  2. Open the markdown preview (Ctrl+Shift+v) and slide it to the right half of the editor (side-by-side view).

  3. Edit the markdown file.

Expected: The code view should always stay in the same position unless the user scrolls the code or preview.

Actual: Just typing in the code makes the code view and preview jump arround erratically.

@dime10 do you have an example markdown page in a repo we can repro this issue with?

same bug

dime10 commented 3 years ago

@bharney0 Sure, this file for example seems especially egregious.

@bharney0 This PR shows it really well. (Microsoft internal)

I'd like to be able to merely thumb-up the OP on this, but this makes the extension very difficult to use, and this issue has been here since 2001. How about fixing it?

Merely scrolling the preview panel or the code (not just editing the markdown) causes this problem that jumps you back in the article. Closing and re-opening the preview helps, and scrolling slowly works a lot better than fast scrolling, but the problem remains with either the preview panel or the markdown jumping you back up as you scroll down the article.
