Editor: actions like undo on a post with embeds auto-scrolls the post when it shouldn't

[ryanboren]

Steps to reproduce

1. Starting at URL: https://wordpress.com/post/
2. Compose something in the editor that contains embeds, blockquotes, and lists
3. Paste something
4. Press Cmd+Z to undo
5. Notice browser reflow that loses your vertical scroll position and sometimes your cursor position

What I expected

I expected undo to remove what I pasted without causing reflow or losing scroll and cursor position.

What happened instead

Undo lost my place. I had to scan and scroll to find where I was before undo.

Browser / OS version

Latest production versions of macOS and Chrome

Context / Source

I experience #undo-reflow often in my sessions. I use undo often, particularly when accidentally pasting something with formatting intact when I meant to Shift+Cmd+z to paste and match style. Experiencing reflow and the loss of scroll and cursor position every time I undo makes for a #frustrated experience. After every undo, I have to scroll and scan my document to find where I left off, often losing my memory state and flow in the process. #scroll-scan-correlate

I was, however, able to reproduce the problem where adding an embed to a post that already has embeds causes the editor to scroll you out of your editing place and it's confusing when that happens.

Hi! I'm performing triage on older bugs as part of the Quality Squad's efforts to cut down on backlog issue counts.

This seems to be the Calypso editor. I am closing this since we are no longer using it and there does not seem to be such an issue in the block editor.
