Hi, reproduce issue with Google Pixel 3 XL (Android 9) on Beta 4.3.0-beta.1 .

Reproducible also on 5.0.0-beta.1 - in normal browsing.

Not sure if this is the same issue but it looks like if a link opens in a new window while in a custom tab, then it looks like a new custom tab and the buttons are greyed out. Pressing the device back button "closes" the custom tab, but then takes you back to your original custom tab. It's definitely weird behavior.

So for example clicking into different articles on bbc.com -> all open in same custom tab window, back + forward buttons work.
Clicking an ad on bbc.com -> opens as a new tab, strange custom tab menu behavior.

Maybe the solution here is just to open all links in one tab for custom tabs since it's really supposed to be one window anyway and there's no way to tab switch.
