Low priority issue but it's in my chrome console.
In stock overview, pick a product and purchase more of it to open the purchase modal.

But I think that doesn't break anything, or does it?

There are many more JS errors from the used third party libraries and different places - as long as they don't break anything, I don't really care about them...

As far as I can tell it does not break anything.
I just wanted to log the information I found in case you didn't know about it or saw an easy workaround to it in the bug discussion.
