At the bottom of a Wikidata statement there is a button that expands the sources section, containing the text "(number of sources) source(s)" and a small arrow which points to the right if the section is collapsed, which is the default if the statement has at least one source. In RTL languages, the arrow still points to the right, instead of pointing to the left. Oddly, collapsing and then expanding the section corrects the arrow so that it points to the left.
I dug into the code and found the reason and a nice and simple enough workaround. Hope I can submit my fix on Monday.
