W3C test html5-002: where did the spaces go?

Consider just the first case:

<div  dir="ltr">&#x5d0;  &gt;  <bdi><br/></bdi>  &gt;  &#x5d1;...</div>

The expected output is described as:

<  &#x5d0;
&#x5d1;  <...

Where did the spaces around the <bdi> element go? where they collapsed 
because they are next to the <br/>? That's the only explaination I see 
for the one after, since it would otherwise be between the < and the 
..., i.e. not at the beginning or end of a line.

Thanks,
Eric.
