**Describe the bug** On Notion, the position of the side menu is positioned at the start of each block, as shown below. <img width="756" alt="Screenshot 2023-10-19 at 16 27 33" src="https://github.com/TypeCellOS/BlockNote/assets/6868147/d0ca3e4d-9147-4a97-ae71-6af5932612f2"> In BlockNote, the side menu is positioned in the _middle_ of each block, which is inconsistent with the notion-like behaviour it aims to be similar to.  **To Reproduce** Just create a multi-line block and hover over the paragraph.
