Description:
I want to prepare a Latin text with the corresponding vocabulary and grammatical comments on the same page, with LO writer in order to have the possibility of post editing. Text, vocab-list and comments are prepared by other programs. To do that I prepare a template with three sections: one for the text, the second for the vocab-list and the last. Then I repeat that group of three sections on the next page.

To fill easily the sections, I convert the odt template to a html and recognize the tags <div id="Texte">...</div> and <div id="Grammaire"> etc... where I have to put my text, vocab and comments. Then, the last easy step consists in loading the html file into LO Writer and save as odt. It works apparently fine.

EXCEPT that the sections are now NESTED. The third one is a sub-section of the second. The fourth one and the fifth one are sub-sections of the third. And the last one is a sub-section of the fifth.

This is the case with two pages, i.e. six sections. What will happen with 100 pages ?

Steps to Reproduce:
1. Create a odt file with three sections, in the attached example they are called "Texte", "Grammaire" and "Definitions" (the text has a single column format, while the two others have two columns). Copy these three sections at the end of the document, they become "Section1", "Section2" and "Section3". The structure of the sections is flat (see Sections_in_template.png). Save that odt for reference.
2. Save as html this same file. Close that window.
3. Re-open the html file. Almost every thing seems OK (except for the header and the footer that are not present on each page, but it is easily restored). But looking at the structure of the sections they appear NESTED (see Back_in_Writer.png), as if a closing tag </div> has escaped to the detection.

Actual Results:
Nested sections (see Back_in_Writer.png). 
As if the html file contained 
<div id="Grammaire">...
    <div id="definitions">...
    </div>
while it contains
<div id="Grammaire">...
</div>
<div id="definitions">...
</div>


Expected Results:
The same flat structure of the sections as in the original odt file (see Sections_in_template.png)


Reproducible: Always

Additional Info:
As I save from odt to html and open again the html file in LO writer (even doing nothing in between), I expect a structure of the sections similar to the original one.
