Description of the problem

Changing the code does not update the output screen.

How has this issue affected you? What are you trying to accomplish?

I am trying to use CodeSandbox for my programming reference website ( https://webcodingcenter.com/ ), by allowing the visitor to test various codes on the fly.
I may be forced to switch to another code editor if the bugs persist.

To Reproduce

Edit the code and notice the output doesn't change even on refreshing.

Your Environment

Start by reproducing the issue in the linked CodeSandbox using the supplied Chrome and Windows environment, then trace the output update path in the codesandbox-client repository. Confirm that editing the code and refreshing updates the rendered output; the payload does not name a file or test to use.
