Progress Wiped

[for-comments]

My computer timed itself out while I was walking the dog, when I came back and tried to continue my work it was gone. The backup button doesn't do anything, and I didn't take any screenshots so I can't even recreate it. This was for an assignment and I need to turn it in today, I can't make it from memory.

Steps to reproduce the bug

1. go to piskelapp.com
2. draw something
3. go to a different tab
4. leave keyboard for something else
5. come back and turn on the computer
6. click on piskel tab
