[Bug] Mobile: 4 Document Bugs!

- [x] If pasting a text into a document, you can't go to the first letter at the beginning with the cursor. And if you do decide to go to the second letter and then delete the first letter, it goes one line up.https://github.com/AppFlowy-IO/AppFlowy/assets/136966318/8587469b-7d58-4f01-9b28-e2883804f832
- [x] Now this brings me to the second problem. The space between each line. Sometimes the space is big, normal or small if also pasting a text into the document.
- [ ] If I want to delete a text while holding the delete button and swipe it to the left, the marking isn't showing up.https://github.com/AppFlowy-IO/AppFlowy/assets/136966318/0822a1c3-5e65-4744-be97-1683b4a79253
- [ ] If I want to copy something it completely goes down the page and marks everything or moves very fast around.https://github.com/AppFlowy-IO/AppFlowy/assets/136966318/c3a95549-cced-474c-9f35-e49a2b111e23
- [ ] If I want to write a number at the start of the line it automatically goes into the list mode and there is no option to turn it off or removing the list.https://github.com/AppFlowy-IO/AppFlowy/assets/136966318/25822faa-7e82-4b52-9e24-50392474042d
