Bug Description

[on mobile, PWA with chrome]
It has been multiple times that I lost the content that I add to my memos by editing it and then multitasking to another app to copy something and then coming back to memos and I find a blank page (no memos). I need to refresh to see my memos and then while editing back the same one, my unsaved changes have been lost.

This is really annoying. I don't want to same my memo each time I multitask between different apps.

I don't know if my explanations are clear. I can provide a video clip to show you what is going wrong.

Steps to Reproduce

1. Install memos as a PWA on android with chrome
2. Login and create a new memo. Save it.
3. Edit this newly created memo by clicking on the 3 dots then Edit
4. Add new things to the memo
5. Multitask to another application without saving the modifications then come back to memos
6. You should see an empty screen (no memos) (it does not always happen, maybe after few minutes editing the same memo)
7. Refresh the page to have the memos back
8. Edit the previously edited memos
9. Your unsaved changes should not be present...

Expected Behavior

I expected either a non-black screen were I can continue to edit my memo OR the unsaved content of my edit to by cached to be able to persist after a refresh.
