Concerning the background ...

  \setupinterlinespace[medium]

is different from for instance

  \setupinterlinespace[line=20pt]

The first case is used for a (more or less) temporary increase and 
leaves \lineheight untouched; this means that lineheight related 
settings stay as they are, which is intended behavour: consider for 
instance a situation where one wants to have a draft copy with a larger 
line distance but at the same time wants to keep (lineheight related) 
graphics untouched.

In your case, you want it as a stye/document property, and so it's 
better to use the second method.

Now, concerning backgrounds: i need to fix that for the first case (use 
\openlineheight instead of lineheight in calculations) [you may enter an 
bug entry in the collector]

For the moment use \setupinterlinespace[line=20pt] or something like that
