[dev] Browser console errors "Minified React error #…"

I just noticed in my browser there's some React errors when loading the page:

Here are the URLs from the screenshot (for convenience):

• https://react.dev/errors/425

• https://react.dev/errors/418

• https://react.dev/errors/423

It's probably not a serious issue, but I have noticed some other scroll jank when loading a page (it scrolls to the top sometimes), so there's a remote chance it could be related to something like this.
