Lists don't flow around WRAP-boxes

[erik-alm]

Placing a WRAP-box next to a list will not make the list wrap around the box, e.g.

<WRAP right half box>
Some text.
</WRAP>

  * Some list with lots and lots of text ... etc.
  * Etc.
  * Etc.

The list will, if it continues below the box, still be half the width of the page.

I have verified that the list do float around the box in the standard theme. I've seen these problems in Bootstrap3, Bootswatch Darkly and Journal. I'm using release 2018-04-22c "Greebo".
