Timeout just in the first load with Angular 18 and SSR

リンクされている lacomanda-front の最小再現をクローンし、記載されている Angular、Firebase、AngularFire のバージョンで / の初回ロード時のタイムアウトを再現します。@angular/build/src/utils/server-rendering/render-page.js に示されている SSR のレンダリングパスから始め、最初のリクエストとリロードを比較します。ローカルおよび Firebase App Hosting で、初回ページロードが 30 秒のタイムアウトなしにレンダリングされれば完了です。

Version info

Angular: 18.0.5

Firebase: latest

AngularFire: 18.0.1

How to reproduce these conditions

Clone this minimal reproduction repository containing just a boostraped project that use Firebase to get the SEO data for a page:

https://github.com/quedicesebas/lacomanda-front

Sample data and security rules

I'm just loading the SEO meta tags info form firebase.

You just need to use this two documents:

brandDomains/lafocachera.co
{"brandId": "lafocachera"}

seoConfigs/lafocachera
{
"meta":
"card": "summary",
"description": "FOCACCIA Y PIZZA AL TAGLIO. Para llevar o DIRECTO A TU CASA",
"image": "https://lafocachera.co/assets/lafocachera/meta.jpg",
"type": "website",
"url": "https://lafocachera.co/"
},
"title "La Focachera - Domicilios MOSQUERA FUNZA Y MADRID"
}

Debug output

I got this just the first time. If I press F5, reloads well each consequent time.

Page / did not render in 30 seconds.

Actual behavior

Timeout the first load (in local and deployed to Firebase App Hosting also)
