1830774 - Closing a custom tab results in all tabs getting closed

Status: NEW

(Focus :: General, defect, P3)

Description

[:randomguy01]

User Agent: Mozilla/5.0 (Android 13; Mobile; rv:109.0) Gecko/112.0 Firefox/112.0

Steps to reproduce:

1. Start Firefox Focus from launcher
2. Open any site, for example mozilla.com
3. Move to another app, for example Telegram
4. Click a link (for example example.com) there to open it in Firefox Focus
5. This spawns a custom tab
6. Move to Android's recent apps screen, swipe the custom tab out

Actual results:

These steps result in closing all tabs.

Expected results:

Only the custom tab (tab opened from another app) should get closed.

(Wanted to attach a video showing the issue, but despite its size being under 50MB, the site timeouts)

Also can't attach a video with size of 4MB after creating the bug report, same gateway timeout.

I could reproduce this issue as described on the latest Focus for Android versions (Nightly 126.0a1, Beta 125.0b9, Release 124.2.0 and 125.0 build 1 with Google Pixel 6a (Android 13).
I was only able to reproduce it with Telegram as the 3rd party app from which the custom app was opened (the issue was not reproducible with Gmail).
