Deleting a tab character using backspace doesn't work. #275754
Description
Type: Bug
If you set "Indent Using Spaces" to 2, set "Change Tab Display Size" to 8, and try to delete the tab character " " (\t) using the Backspace key, it won't be deleted. The character can be deleted using the Ctrl+Backspace shortcut, and the character can also be deleted by moving the cursor past the character and trying to delete it using the Delete key. This error also occurs in VS Code Insiders.
