Bookmarks disappear when VS Code is reopened

[PeterMacej]

Type: Bug

I searched all similar issues and I think mine is the same as #538.

To reproduce:

1. Create a simple file c:\test.txt with a single line "abc". It's a standalone file, not a part of a project, folder, or workspace.
2. Toggle a bookmark on this line. The bookmark is correctly created and works fine.
3. Close VS Code.
4. Open the file in VS Code. The bookmark is missing.

Expected behavior:
The bookmark should be visible in step 4.

I don't use Pretier.
I did some tests and inspected the VS Code storage with DB Browser for SQLite. After I closed VS Code, the bookmark data was still present in \Roaming\Code\User\workspaceStorage\1666599132300\state.vscdb:

When I re-opened the file in VS Code and then closed VS Code, the data was removed:

So the problem occurs when VS Code or the file is open.
