At the very least the adblocking aspect should be sanity tested after this change

[Uni-verse]

Verified on iPhone 12 running iOS 17.0.3 using version 1.58 (23.10.17.8)

Sanity tested the following areas

Content ads / Video ads

• Ensured that content ads are blocked on youtube.com, x.com and other sites with default settings on fresh install.
• Ensured that preroll ads are not shown for youtube videos when Shields are up. Bringing down Shields will show the ads.
• Ensured adblocking is working in standard and aggressive modes
