Steps to reproduce the issue

• Note: In Global Configuration -> System, "Shared Session" must be disabled to reproduce the issue
• Create a Menu Item of type "Users » Edit User Profile", call it "Edit Profile"
• Keep the backend open in a browser tab
• Open another tab, go to the frontend, click on the "Edit Profile" Menu Item
• Simply save your profile from the frontend by pressing "Save"
• Go back to the backend tab, refresh. You've been logged out of the backend.
  (on the other hand, you're still logged-in the frontend)

Expected result

You should not be logged out of the backend just because you edited your profile. That makes no sense.

Actual result

You are logged out from the backend by just editing your profile from the frontend.

System information (as much as possible)

Can be reproduced on all Joomla 4.x versions, including 4.4.x, as well as the newest Joomla 5.x
