[Bug 1943037] [NEW] Automounts do not reset properly after TimeoutIdleSec automatic unmounts

[Fernando]

Public bug reported:

Ubuntu version: Ubuntu 20.04.3 LTS
systemd version: 245.4-4ubuntu3.11

Expected behavior:

Automount units whose associated mount units have been auto-unmounted
with TimeoutIdleSec will trigger the associated mount unit when the
automount path is accessed again

Current behavior:

Automount units whose associated mount units have been auto-unmounted
with TimeoutIdleSec do not trigger the associated mount unit when the
automount path is accessed again until the automount unit is completely
restarted.

Steps to reproduce the problem

1. Trigger any automount unit with TimeoutIdleSec= set
2- Wait for the idle time to occur and systemd to unmount the associated mount unit
3. Then try to access the automount location again.
