The draft should not be lost when page is open for too long

[frol]

Describe the bug

I received this report from Guillermo initially, but today I faced the same issue myself and I guess I know the root cause.

I was writing an attestation on a Post page (not feed, if that matters at all), and I got into a call for 1 hour. After I got back to the tab, I saw it getting quickly refreshed and my attestation is gone.

To Reproduce

Steps to reproduce the behavior:

1. Go to Post page
2. Start writing a response
3. Switch to other tabs for a while (in my case it was 1 hour)
4. Get back to the tab and see that the response is gone (the reply box is closed)

Expected behavior

Even if the page is refreshed, I should see my draft there.
