Fragmented lists - Invalid numbering and broken if above 10

[Pantoofle]

Describe the bug When displaying an fragmented ordered list, the numbering of the source is not respected, making it impossible to have an ordered list not starting at 1. Moreover, items of fragmented lists with index above 10 are not fragmented.

Samples to Reproduce Steps & Examples to reproduce the behavior: On this minimal example:

8) This should be 8.
9) This should be 9.
10) This is not detected
11) Same problem

The resulting slide will:

• Always display items 10 and 11
• Display items 8 and 9 as 1. and 2.

Expected behavior

• The item numbers written in a numbered list should be respected and not re-numbered
• Items with a number above 10 should be detected as parts of the list
