PUSH service do not properly restart if process com.fsck.k9 is killed (some OS kill it if app is removed from recent window, even if a service is running)

App

K-9 Mail

App version

8.2

Where did you get the app from?

F-Droid

Android version

14

Device model

Jelly Max

Steps to reproduce

1. Turn on Push for inbox folder (with relative permission to schedule alarm)
2. Launch App
3. Close App
4. notification bell in status bar disappear and after few seconds appear again
5. send mail
6. no notification
7. pull down notification area and click on Waiting for new emails and then Tap to learn more (informative windows appear)
8. notification for previous mail arrive immediately

Expected behavior

If there is notification service active and bell notification icon i expect that push notification should work.

Actual behavior

Seems that when application is closed, imap idle connection is closed too, then bell notification reappear but push notification do not work anymore until i click on "tap to learn more".

Logs

It's a strange behavior, consider that the push service is always running i can see from Android "Developer Option/Running service" that it's never stopped, it's even listed in "Active Apps" warning with running time equals to boot time (i attach a screen).
I own the mail server that i use for imap push, so i have looked at the mail logs; when application is stopped IMAP idle connection is closed.
Then even if bell icon reappear in notification status bar, connection is not re-established until i click on "Tap to learn more".
As soon as i click on "Tap to learn more" imap connection is established and if there are pending emails i am immediately notified.

Reproduce the issue using the listed Android 14 steps, focusing on the push service after the app process is killed and the IMAP IDLE connection closes. Start by tracing the push service lifecycle and the “Tap to learn more” notification action. Done means the connection is re-established and new-mail notifications work without tapping that action.
