If you put the following HTML containing an Arabic paragraph and ordered list with nested unordered list, (stolen from the translation of our Problems logging in? post), and the English version of the same text, into a work, the Arabic list will be aligned with the right edge of the text. However, for the English, the edge of the list is indented 1.75em from the left edge of the English paragraph.
The Arabic list should have the mirror image of the English list’s indenting – that is, items should have a margin of 1.75em on the right and 0em on the left. Refer to attached screenshots.
This is similar to AO3-5737.
Seems to work as expected.
