does not generate properties, only base element

the documentation states the following (left column being input and right being output):

b[x]                     <b x=""></b>
b[x=]                    <b x=""></b>
b[x=""]                  <b x=""></b>
b[x=y]                   <b x="y"></b>
b[x="y"]                 <b x="y"></b>

Unfortunately, when trying to use these examples, even when pasting the input verbatim into my buffer, the output I get only yields <b></b> for all five of the above cited cases.

I'm unable to replicate this - could you tell us what major-mode and any other minor-modes that are active?

The active major mode in this buffer is Web-mode and describe-modes yields this list:
