Ad Tracker doesn't completely block an ad, website loading is delayed by ad timeout

[omeryarko]

Steps to reproduce

Firefox Focus for iOS, latest version (112)
Browse to ynet.co.il/

Expected behavior

Website loads normaly, without ads, within moments.
This is a major news website that I used to access several times a day without any issues until recently.

Actual behavior

Firefox focus seems to stop loading the website, but the screen is all white. After approximately 30-45 seconds, the website loads OK without ads.
Only after disabling Ad Tracker, the website appears on screen (with ads).

Device & build information

• Device: iPhone 11
• Build version: 112.0 (16904) / iOS 16.3.1
