Blank page for few seconds on initial load

[wooque]

Description

Some websites have delay in showing full page, they show as blank white page at first and after few seconds they reveal in full. Inspecting it I noticed that html tag has async-hide class that is removed after few seconds and that lead me to past issue that seems to be back again #4402

Steps to Reproduce

1. Open https://www.kupujemprodajem.com/index.php

Actual result:

It shows blank white page, after few seconds it shows fully

Expected result:

No artificial blank white page delay

Reproduces how often:

I had similar issue on accuweather.com and I solved it with customer filters

accuweather.com##+js(remove-attr, class, .ads-not-loaded, stay)
kupujemprodajem.com##+js(remove-attr, class, .async-hide, stay)
polovniautomobili.com##+js(remove-attr, class, .async-hide, stay)

@wooque is this still happening?

Sorry I missed the post, has these delays always been here? just tested FF on https://www.polovniautomobili.com/auto-oglasi/19998599/bmw-520?attp=p8_pv0_pc1_pl9_plv0 Noticed a delay here also @wooque

||googletagmanager.com/gtm.js$script,redirect-rule=googletagmanager_gtm.js:5 from uBO prevents the delays, we are implementing uBO redirect-rule soon-ish which should help

In Brave Nightly, add these to brave://adblock

||securepubads.g.doubleclick.net/tag/js/gpt.js$script,redirect-rule=googletagservices_gpt.js
||googletagmanager.com/gtm.js$script,redirect-rule=googletagmanager_gtm.js
||google-analytics.com/analytics.js$script,redirect-rule=google-analytics.com/analytics.js

Should fix the delays

@bsclifton yes, it's still happening
@ryanbr for accuweather.com and kupujemprodajem.com it started relatively recently, didn't saw delays before. I don't know if they changed something on their sites or it's Brave Shields regression.
Note: Accuweather is not blank page but it shows artificial loading animation for few seconds before it shows full content https://www.accuweather.com/en/rs/belgrade/298198/weather-forecast/298198

Luckily found workaround with ##+js(remove-attr, class, .class, stay) until those redirect rules are added

@ryanbr Fix has a bug, only accuweather.com is fixed by removing .ads-not-loaded, kupujemprodajem.com i polovniautomobili.com are fixed by removing .async-hide
