4. Tap on Show Brave News button from news card on NTP
5. It shouldn't crash

++. That's cool, we have users who experience that crash and I see it in GPS as well. We want to uplift it up to a stable channel as it's a problem there as well.

Verified PASSED using 1.50.9, Chromium 110.0.5481.77 on a Google Pixel XL (arm64) running Android 9

Steps:

1. installed 1.50.9
2. launched Brave
3. disabled Wi-Fi
4. tapped through onboarding
5. swiped up on the new-tab page
6. tapped Show Brave News

Confirmed Brave restarts now, rather than hard-crashing, when it hits this case

1.50.9	1.49.77

Didn't see #17012 (comment) before checking so quickly went through the above as well and verified that everything seems to be working. Went through a few other cases to ensure everything was working as expected.

Verification PASSED on Pixel 6 running Android 13 using the following build(s):

Brave | 1.50.11 Chromium: 110.0.5481.77 (Official Build) canary (32-bit)
--- | ---
Revision | 65ed616c6e8ee3fe0ad64fe83796c020644d42af-refs/branch-heads/5481@{#839}
OS | Android 13; Build/TQ1A.230105.002

• ensure there's no crashes when enabling/disabling Brave News while the network is disabled and the feed never loaded
• ensured that enabling the network loaded the news feed when opening a NTP without any issues
• ensured that you can scroll through the news feed without any issues
• ensured that you're seeing Brave Ads within the news feed
• ensured that tapping on articles opens them within the same tab without any issues
