I‘ve verified this issue using the latest Firefox Nightly 106.0a1 (Build ID: 20220825222149) on Windows 10 x64, macOS 12.5.1, and Linux Mint 20.2 x64.

• The elements from the first screen of the Firefox View Tour feature no longer overlap with the ones from the “Independent Voices” section when resizing the browser on RTL builds.
