Yeah I don’t get it either.

I kept reading it expecting something to jump out at me. He just goes on about how “a square cannot be rotated”.

This honestly feels like more of a chrome bug or more likely some really weird settings on behalf of the author. I’ve seen this exact approach on the web. Nothing struck me as odd.

What is odd is that he didn’t do any testing with a different browser, machine, or OS even. He just decided to make a blog post.

Would be interesting if you could prevent pulling down “private” code if you were working on something from the “public” side

Yes sort of how you can pull shallowly
