1. in insert mode
2. hit tab
3. hit escape

5. delete the newly inserted tab (x)
6. see the line retreat the size of the tab.

Expected behavior

2. hit tab
3. hit escape
4. see the little tab highlight flash.

Additional context
Add any other context about the problem here.

Start by reproducing the issue in VSCodeVim on Linux: enable the generic setting that converts tabs to spaces, then follow the listed insert, escape, and delete steps. Compare the result with the expected behavior; done means deleting the inserted tab retreats the line by one character rather than the full tab width.
