I think the behaviour is correct.

videomixer always generates output with the size that is requested via caps
downstream of videomixer. And into the size it places the input videos (of
which you can modify the locations inside the output video).

If you want scaling you either need to do it before videomixer, or explicitly
after videomixer:

... ! videomixer ! "video/x-raw,width=300,height=150" ! videoscale !
"video/x-raw,width=600,height=300" ! ...
