Description of the Issue

The session file that Notepad++ can use to remember opened files gets reset to an empty template after opening and closing one. This behaviour never happened before.

Steps to Reproduce the Issue

1. Open a previously saved session file (with some tabs and such) using Notepad++ 8.2.
2. The files get opened in their tabs as usual.
3. Close Notepad++.

Expected Behavior

The file should be untouched. Notepad++ 8.1.9.3 doesn't have this problem.

Actual Behavior

The session file is clean except some markup lines.

Debug Information

This is the content of the emptied session file:

<?xml version="1.0" encoding="UTF-8" ?> <NotepadPlus> <Session activeView="0"> <mainView activeIndex="0" /> <subView activeIndex="0" /> </Session> </NotepadPlus>
