Markdown previewing tab not binding to the specific file when multiple .md files are in different subfolders

[Seeker98]

Does this issue occur when all extensions are disabled?: Yes

Steps to Reproduce:

1. create a new empty folder, open with code, create a new .md file, (lets say 1.md), write "test" in 1.md and save.
2. create a child folder (let's say child_folder), and create a new file same name to above (1.md) under the child folder, write "test_child" in ./child_folder/1.md and save
3. close all tabs
4. open ./1.md, and ctrl+shift+v to open preview, now the preview window shows "test"
5. open ./child_folder/1.md, and switch to the preview window (which should display the preview of ./1.md), now it shows "test_child". but we assume it to keep showing "test".

This bug (probably?) also reproduces under ubuntu 22.04 with same version and all extensions disabled. If creating more subfolders and more .mds with same name, the preview window always shows content from the last file checked.

this is a visualization of the folder structure and file content.
