<bdi>
Isolates a run so its direction does not contaminate the sentence.
Names, titles and other data coming from outside may be in Arabic or Hebrew. Without isolation, the Unicode bidirectional algorithm reorders the surrounding text and the sentence comes out scrambled — punctuation in the wrong place, numbers out of order.
<bdi> turns the run into an island: its direction is worked out inside it alone and does not leak. In practice it is dir="auto" with containment.
