Block note is not WYSIWYG

Reproduction steps

1. edit a page
2. change some elements
3. save
4. observe if the result is displayed identically

Expected

The result is identical (or at least really close) in edit and view mode

Actual

The result has significant differences since the content is styled:

• by the design system in view mode
• by Blocknote own style in edit mode

Differences can be seen for:

• Numbered lists
• Bullet lists
• Checked lists
• Code blocks
• Quote blocks
• Headings
