Wrong cursor position after using same file in two panels

Describe the bug
This is the same as #2688, which, according to the ticket, was fixed at least 5 years ago. I'm observing it now. I'm a new vscode user, I've been using it for a few months and I don't use split panels very often, so I'm not certain whether it has been doing it since I originally installed it (most likely) or whether it started doing it later.

To Reproduce
Steps to reproduce the behavior:

1. Open a file
2. In normal mode, type ":split".
3. While you are in the top pane, type 50G to go to line 50.
4. Type Ctrl+W,j to go to the bottom pane, then 300G to go to line 300.
5. Type Ctrl+W,k to go to the top pane.
6. Observe that, in the top pane, the cursor is now on line 300.

Expected behavior
I expected to be in line 50.

Screenshots
Here's a 20-second video that demonstrates: https://www.loom.com/share/78965a1754a7411da9a5c1262456eb18

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.30.1
• VSCode version: 1.103.0
• OS: Debian 13.0 "Trixie"

Reproduce the issue in VS Code with the VSCodeVim extension using the listed split-pane and Ctrl+W navigation steps. Start by tracing how cursor positions are stored when the same file is shown in both panes, and compare the behavior with issue #2688. Done means returning to the top pane restores line 50 rather than line 300.
