QA note: this was fixed in AC, but will not be testable in Fenix until we have a build using the new snapshot.

Hello, I was unable to reproduce this issue using the latest version of Firefox Preview Nightly (1/16 build #20160806) on the following devices:

• Nokia 6 (Android 7.1.1);
• Motorola Moto G6 (Android 8.0);
• Samsung Galaxy S7 Edge (Android 8.0.0);
• Samsung Galaxy Note 8 (Android 9);
• Google Pixel (Android Q).

Due to that, I'll close this issue, thanks.
