Description of the Issue

If the document map is enabled, NPP will not create a "new 2" document but will jump to "new 3".
I believe this is similar to issue #8677 that was fixed.

Steps to Reproduce the Issue

1. Open NPP.
2. Click View > Document Map.
3. Create a new document.

Expected Behavior

See "new 1" then "new 2" in the tab / document list.

Actual Behavior

See "new 1" then "new 3" in the tab / document list.

The issue no longer occurs when the document map is disabled.
Probably not high priority, just a mild inconvenience for me. I copy paste into 10+ documents at a time from other sources "output1.txt" to "output10.txt" etc, and like to use the document map. It would be easier to align source and destination documents if they were created as "new 1-10" instead of "new 1" then "new 3-11".
