The 508 changes to "hide" content off to a negative left position is incorrect when handling rtl languages. For rtl languages it should be placed at a negative right position instead.
With older android browsers there is an issue where it expect a positive right position for this hack to work. A work around will have to be done to deal with this situation.
Without these changes it causes the browser to render the page as it if is extremely wide(10 000px). Some browsers cannot handle this and it causes strange behaviours such as links no longer functioning.
