Dib notebook with a markdown cell is set as edited one second after opening

[marckruzik]

Describe the bug

Every time I open a dib notebook containing a markdown cell, one second later, the file is set as edited. The file should not be set as edited when I do not edit it.

I tracked down the issue to reproduce the bug as simply as possible, with just one markdown cell.

Steps to reproduce the bug:

• launch VS Code
• create a new dib notebook
• remove the code cell
• add a markdown cell with a title "# title"
• save the document in the workspace
• close the document
• in VS Code explorer, double-click on the notebook
• the notebook is open
• wait a few seconds
• the notebook is set as edited

Here is a gif where the notebook is open and set as edited:

@rebornix is there any change on cell metadata behaviour? This looks like something we addressed in the past with metadata flagged as dirty when should not. @brettfo rings any bell?
