Preview site flashes and moves while typing

[samuel-garmany]

Describe the bug
The preview window moves up for every character while typing, making it hard to see a preview. The window also flashes when typing at the bottom of a file after a code block.

To Reproduce
Steps to reproduce the behavior:

1. Install markdown-preview.nvim through lazy (I'm using alacritty)
2. Use firefox
3. Type in the middle of a file to see the movement issue
4. Type after a code block to see the flashing

Expected behavior
The preview should stay exactly where the typing is taking place and not flash when typing, mirroring the editor.
