Automatic updates in the header break the undo/redo history

[n4mr3g]

Steps to reproduce:
1- Open a file in vscode
2- Write some characters in it, in order to create a undo buffer
3- Undo one or more times (ctrl + z)
4- Wait about 5 seconds
5- Try to "redo" (ctrl + y) the changes made in step 2.

Expected result: the user's last actions are restored
Actual result: the user's last actions are not restored, because the header was updated and the "redo" buffer was lost.

Somehow, this wasn't an issue for me until today. I'm just guessing some change in the last version of VSCode is to blame?

VSCode version: 1.68.0
OS: Windows 10 x64
