Just came to report this. This is incredibly annoying, but I have observed that the tab opens and then immediately closes when Fenix is left on the tab overview. Otherwise it just shows a previous tab.

Hi @ekager , I've checked and the webpage is opened in Fenix.
On the other hand, the link from the custom tab doesn't populate the URL bar from Fenix.

I've used the latest Nightly Build #12520610 from 9/9 with the following devices:
• Google Pixel 3a (Android 9)
• Huawei Mate 20 Lite (Andriod 8.1.0)
• Samsung Galaxy S7 (Android 7)
• OnePlus A3 (Android 6.0.1)

Thank you, @AndiAJ, this looks like an important bug - although I think unrelated to this bug fixed here. I can reproduce this in Reference Browser and assume that this is related to our feature-toolbar refactoring that has happened just recently. I filed the following AC issue to track that:

Closing this bug because unrelated to #5169
