Yup. This snippet adds a css animation to make the page white for 8s, and it's stopped by Google's JS or the browser's noscript (which you don't enable if you only block Google's JS and not the domain JS):

Insane. Google has lost all credibility.

So, is there a way that I can block this tag somehow and drop it during the load time?

You can add a Stylus stylesheet enabled for the regex .[star]amp.[star] (replace [star] with the star symbol) that contains body{animation:none}, but I don't know if that's good for performance.

Edit: Developers can also add that css in their amp style, and it seems to be accepted by the amp validator. AMP devs, you know what to do! ;)

Go for this on all pages instead:

  html[\26a1] body, html[amp] body {
    animation: none;
  }

(I wrote \26a1 because HN doesn’t allow the literal U+26A1 character.)

That way it applies to all AMP pages, regardless of their URL, and doesn’t clobber any other pages (though I can’t actually imagine any genuine animation on a body element).

Works perfectly, thank you!

I took the liberty to put it on userstyles.org for one-click install: https://userstyles.org/styles/171953/disable-amp-blank-loadi...

Btw you can begin a line with two spaces for code formatting:

  .*amp.*

I assume the idea behind it is to prevent the “flash of unstyled content”.

I wonder who made the decision that 8s delay is better than the unstyled flash.

Flashes are distracting. IMO, it's not the delay that's the problem, but the fact that it lasts eight seconds. The limit should be 500 milliseconds, at most.

There is no delay if the script loads properly.

Having the delay in that circumstance is much, much worse than a FOUC.

I agree

Consider a very slow network connection. Is effectively delaying the page loading for 8 seconds worth it?

No, but I didn't say it was was a good idea

the original code is to prevent FOUC, that 8 second delay is sort of a fallback if the js hasn't unhidden the body
