Research direction

Start by reproducing the reported sequence in Chrome on Windows: edit a project, sleep the computer for at least 10 minutes, then wake it. Trace the editor's autosave behavior when the page resumes, and verify that waking from sleep does not save an older project version or overwrite newer work.

Description

https://scratch.mit.edu/discuss/topic/898447/

Expected Behavior

When waking up the computer from a long sleep mode, the Scratch editor doesn't save automatically.

Actual Behavior

It tries to save immediately, and sometimes successfully overwrites the project with a (probably) old version. I tried to reproduce the bug many times, and it usually displayed the "project could not save" error, but a few times it actually saved the project

Steps to Reproduce

Steps to reproduce the behavior:

  1. Sign in and go to one of your Scratch projects
  2. Edit it slightly (eg. by moving a block)
  3. Put the computer in sleep mode
  4. Leave it for I think at least 10 minutes (when I left it for only 6 minutes, the Save Now button was still there)
  5. Open the computer
  6. See that Scratch tries to save
