Sandbox goes into infinite loop

[Pyrolistical]

🐛 bug report

I was writing a code sample for my library, and I think I wrote an infinite loop. Now whenever try to open the sandbox, the Chrome tab goes to 100% cpu.

Sandbox: https://codesandbox.io/s/4x9mx64kl0

Environment

Software	Name/Version
Browser	Chrome 67.0.3396.79
Operating System	macOS 10.13.4

If the sandbox didn't auto run every time it opened, I could fix the code.

Another repo case: #50 (comment)

One way to solve this is to for codesandbox to inject a js heartbeat into apps. The heartbeat will fail on load, at which point on next load codesandbox should prompt sandbox history and allow you to revert to a previous version.

I was able to pull the source from the broken sandbox and manually re-create it using the API https://codesandbox.io/api/v1/sandboxes/4x9mx64kl0

I think I am in the same case: https://codesandbox.io/s/v8km1067ml
(sandbox vanilla + jquery & semUI)
NB: when I'm forking the sandbox with the problem, the forked sandbox seems ok.

Looks like I mistakenly made a loop too. https://codesandbox.io/s/vigilant-shannon-veu5b

I'd be cool if you could maybe add a query string like ?safemode=1 that would not auto run the code, so could fix it, save and exit safe mode when ready to run it again.

+1, a query string like ?safemode=1 would be perfect.

@bduffany This already exists, but it's named runonclick, i.e. https://codesandbox.io/s/vigilant-shannon-veu5b?runonclick=1 .
