Calibre rules out shifting ordered lists to the right

[repilo]

Hello, I have a problem with the ordered lists in the epub to kepub conversion (also epub to epub).
I want to shift the lists a bit to the right, so that the item numbers are aligned with the text-indent of the normal p (by default, the item text is what is aligned with p's text-indent).
I achieve this in epub with:

p { margin:.2em 0; text-align:justify; text-indent:9%; }
ul, ol {
	display: block;
	margin:1em 0 1em 9%; /* aligns item text with p indent */
	padding-left:1em; /* shift to align the item number */
}

where with padding-left:1em I get the additional offset I need for the item number.

The problem is that although this looks fine in epub, Calibre discards it when converting to both kepub (which I need) and epub (which I do to test).
The result is:

<ol class="calibre3">
    <li class="calibre4">...

Where:

.calibre3 {
  display: block;
  list-style-type: decimal;
  margin-bottom: 1em;
  margin-right: 0;
  margin-top: 1em;
}
.calibre4 {
  display: list-item;
  text-align: justify;
}

There is no allusion to the left margin anymore.
So how could I achieve what I want, i.e. shift the lists a certain amount to the right?

Thank you very much in advance. I really appreciate your work.

turn off the fake margin removal setting in structure detection.

I already had it turned off (unchecked).
Calibre 6.16, Windows 10.

1. The file you are trying to convert: attached test_list.epub
2. The conversion log from calibre: I can't get it, too fast. There is not any error message.
3. The output file: attached output.epub
4. Description: see the first post. In short:

I want to shift the lists a bit to the right, so that the item numbers are aligned with the text-indent of the normal p (by default, the item text is what is aligned with p's text-indent).
I write the necessary code to achieve this and it looks fine in epub format, but when Calibre does the conversion from epub to kepub, or even to epub, the shifting to the right disappears. There is no allusion to the left margin anymore.

Although my intention is to send the epub to my Kobo, converting it automatically into kepub, the problem also occurs in the epub to epub conversion (the result of which I have attached).

Yes, padding and margin on lists cause rendering problems in some renderers so they are deliberately removed when converting to EPUB.

If anyone is interested in this, I've come up with a workaround by enclosing the list in a div with padding-left.

ul, ol {
	display: block;
	margin: 1em 0 1em 0;
	padding-left: 9%;
}
div.ol1d { padding-left:1.16em; } /* for 1 digit list */
div.ol2d { padding-left:1.6em; } /* for 2 digits list */

  <div class="ol1d">
    <ol>
      <li>Item number is aligned with text-indent of p.</li>
      <li>Item.</li>
      <li>Item.</li>
    </ol>
  </div>

Can they be no longer deleted or made an option with off as the default?
