&vendorShortName; is escaped in ar breaking the referencing of this entity

We have <!ENTITY project.tpoLink "&amp;vendorShortName؛"> in ar's aboutDialog.dtd. Note for comparison, just one line above in that file <!ENTITY project.start "طوّر &brandShortName;">.

The latter is correct as the & and ; are making sure brandShortName as it is translated elsewhere gets included. But that fails if one starts to escape those characters (e.g. by replacing & with &amp).

Thanks to Thorin for reporting this issue.
