Cursor jumps to the beginning of the file after switching from another one

Describe the bug
Sometimes, after switching from one file to another (through tabs), pressing a key makes the cursor jump to the beginning of the file.

To Reproduce
I haven't found yet what's triggering the issue. However, once it happens, it can be reproduced like this:

1. One a file editor, move away from the beginning of the file (row 0, column 0, if you are there), either with the keyboard or with the mouse. For example, press j to move down one line.
2. Switch to another file tab with the keyboard or mouse.
3. Switch back to the previous file.
4. Pressing any key (Esc included) but modifiers (Ctrl, Alt...) jumps to the beginning.
5. Closing and reopening the file fixes it.

Expected behavior
The cursor should remain in the same position.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.24.3
• VSCode version: 1.74.2
• OS: Linux

Additional context
This issue appeared after the upgrade to VS Code 1.74, so it may be related to #8157, although a file affected by the former might not be by the latter.

Start by reproducing the tab-switching sequence described in the issue on the stated VS Code and VsCodeVim versions. Trace the extension's handling of editor changes, cursor restoration, and key events to identify why the first key resets the cursor; done means the cursor remains in its prior position after switching tabs and the regression is covered by a test.
