Don't use line-height ... use padding-after= since you want to keep 
the blue background behind the text.  You would use space-after= if 
you wanted to use the parent area's background colour.

Another approach would be to create a block-container with your 
background colour and then just flow the text into the top of the 
block container.

You are conflating line areas with block areas, trying to do in a 
line area what I think you are witnessing in page areas in other products.

<fo:block> creates a bunch of lines, which is why these properties 
are all going into your line areas.

<fo:block-container> creates a rectangle into which you flow 
<fo:block> constructs, so I suspect you just need to decorate a 
container with what you need.

I hope this helps.
