1. When I finished editing and click "Save" button, I found that the new blocks (not sure if it's called blocks) and content within I just added were missing; while the content added in previously existing blocks are effective
2. This is the first time that I encounter this issue. (But I do encounter another issue of auto duplicate blocks when my page is too long, same for my colleagues)
3. Not sure if anyone else is facing this issue too. I couldn't find my text anywhere, so I had to re-write. Not sure how to reproduce this
