NPP jumps from "new 1" to "new 3" when document map is visible

[RodneyRabbit]

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".

It isn't related specifically to the document map.

Try this alternative StR:

Close the document map if it is open.
Restart N++ so that you have a single document open, new 1.
Press Ctrl+f and do a Find All in Current Document search so that the Search results window/panel appears.
Create a new tab/doc via Ctrl+n; observe that new 3 is created.

The numbering has to do with how many "Scintilla" buffers are open.
The Search results window is a Scintilla buffer.
Document Map is apparently also a Scintilla buffer.

The real intent of tabs named "new X" is to just give you a quick starting point for creating a document, and that you should save to a hard-named disk file as soon as possible. If you make this a part of your workflow, it doesn't matter what the "new X" tabs are named. Sure, you're not forced to do this, but it is a reasonable workflow.

EDIT: I didn't look at issue 8677 before composing the above response. My example here was the same as 8677! :-)
