<title>HTML Test: BDI: neutral to surrounding letters</title>

<meta name="assert" content="
'For the purposes of applying the bidirectional algorithm to the paragraph-level
container that a bdi element finds itself within, the bdi element must be treated
like a U+FFFC OBJECT REPLACEMENT CHARACTER.'
Thus, regardless of its content and its dir attribute (if any), a BDI will not prevent
a strongly RTL (or LTR) character preceding it from forming a single directional run with
another strongly RTL (LTR) character following it."/>

Key to entities used below:
א ... ו - The first six Hebrew letters (strongly RTL).
‭ - The LRO (left-to-right override) formatting character.
‬ - The PDF (pop directional formatting) formatting character; closes LRO.
If the BDI in the test's first DIV were a SPAN, its b would prevent the א and the ב
from forming a single RTL run and thus keep the >s between from being mirrored into <s.
