Describe the bug
I tried to use your edit docs button/app, did not work.

To Reproduce

1. Go to https://developer.stackblitz.com/guides/integration/open-from-github
2. Click on Edit Page (at the bottom)
3. I made a suggestion:

That page says that github and github.com in the stackblitz/github/ URLs are equivalent. However, if you're using the stackblitz.com/fork/ variant, you cannot use /github.com/ (404s), it MUST be just /github/.

4. I pressed the Fork and Commit button, or whatever the green button was in the top right corner. There was a popup, I clicked both. The button appeared unresponsive, I clicked it 4 times before leaving.

Expected behavior
Some sort of confirmation that my time wasn't wasted?
