Problem description: 

User defined header styles do not behave as default header styles. The user needs to demote or promote each header paragraph in the text editor to the right level, even if the new styles know their right Outline level from Format > Styles and Formatting > Paragraph Styles
I add that outline level is correctly used by automatic table of contents.

This bug could be similar to:
https://www.libreoffice.org/bugzilla/show_bug.cgi?id=62032

Steps to reproduce:

1. Open: Format > Styles and Formatting > List Styles

2. Create new numbering style "Outline numbering for appendix"
perfectly identical to the wired "Outline numbering" except for numbering of the first level: use letters instead of numbers (eg. Appendix A)

3. Open: Format > Styles and Formatting > Paragraph Styles
and create new styles "Heading 1 Appendix", "Heading 2 Appendix", ... linked with corresponding "Heading 1", "Heading 2", ...

4. Set for each new style the correct Outline level:
- level 1 for "Heading 1 Appendix",
- level 2 for "Heading 2 Appendix",
- ...
and Numbering style: "Outline numbering for appendix"

5. Back in the text create a new headers for appendix: "Title of appendix level 1", "Title of appendix level 2", ...
then assign the right new style to each one: "Heading 1 Appendix", "Heading 2 Appendix", ...


Current behavior:

In the text, both "Title of appendix level 1", "Title of appendix level 2" appear as level 1:

A. Title of appendix level 1
B. Title of appendix level 2

I have to demote "title of appendix level 2" to obtain the desired behaviour:

A. Title of appendix level 1
A.1 Title of appendix level 2


Expected behavior:

I expect this second behavior automatically:

A. title of appendix level 1
A.1 title of appendix level 2

Each new appendix heading style knows its Outline level from Format > Styles and Formatting > Paragraph Styles

There should be no need to demote the appendix heading to obtain the desired behavior.

These new headings (eg. "Heading 1 Appendix"...) should be treated as much as possible as the default ones from Tools > Outline numbering

Thank you very much for your kind attention.
