When copy all contents of a file to another, the two files become linked

[JetStarBlues]

Nature of issue?

• Found a bug

Details about the bug:

• Web browser and version: Chrome 91.0.4472.77 (64-bit)
  • I was not able to reproduce this behaviour on Firefox 89.0 (64-bit)
• Operating System: Windows 10

Steps to reproduce this bug:

• Step 1
  • create a new file (thecopy.js)
• Step 2
  • copy all of the contents of sketch.js to this new file using:
    • ctrl-a, ctrl-c, ctrl-v
• Step 3
  • edit the original file (sketch.js)
  • The bug:
    • changes made in the original file are reflected in the new file (thecopy.js)
      • the files have become linked somehow
    • a simple refresh doesn't seem to clear this link
      • sort of (this is tricky to track down, sometimes a couple of refreshes does clear)
      • a "hard reload" seems to clear the link

Maybe somewhere along the line, instead of a true copy (deep), the file contents are just copied by reference (shallow).

I've encountered this bug a couple of times, when attempting to "save" existing work and create a new copy where I'm free to delete/change etc. Or when wanting to use one file as a template.

Thanks for reporting! I am able to reproduce. I'm going to do some investigating and see if I can figure out the root cause.
