Steps to replicate the issue (include links if applicable):
Try use the compact_items gadget on wikidata, https://wikidata.org/wiki/MediaWiki:Gadget-compact_items.css
with hebrew https://www.wikidata.org/wiki/Q42?uselang=he
and try to add reference.
What happens?:
background-image:url(//upload.wikimedia.org/wikipedia/commons/5/5b/OOjs_UI_icon_quotesAdd-rtl.svg)
(caused by the convert "ltr"→"rtl").
But: the //upload.wikimedia.org/wikipedia/commons/5/5b/OOjs_UI_icon_quotesAdd-rtl.svg gives the error message:
File not found: /v1/AUTH_mw/wikipedia-commons-local-public.5b/5/5b/OOjs_UI_icon_quotesAdd-rtl.svg
So
.wikibase-statementview-references .wikibase-toolbar-button-add .wb-icon on hebrew is not visible.

What should have happened instead?:
EN:
Use https://upload.wikimedia.org/wikipedia/commons/2/2d/OOjs_UI_icon_quotesAdd-rtl.svg or do something else like fixing the conversion to make it visible.
