I know extremely little about RTL rendering, but it looks to me like if URLs are always meant to be interpreted as LTR, then they should be wrapped in <span dir="ltr"> any time the context is RTL. Perhaps this could be added heuristically (like how automatic linking happens heuristically) by wysiwyg inputs.
