dialog (not in fullscreen) is taking all screen

Im trying to show the FullScreenDialog as a normal one, meaning i want it to wrap the content in my dialog fragment and not take the all screen.
of course i user setFullscreen(false) and got the "normal look" dialog, but it still takes the whole screen with only the edges around shows the background parent.
how can i change the height of the dialog to only wrap the content (like normal dialog)?
ive tried looking for it in the code with no success.

thank you!

Start with the FullScreenDialog implementation and the setFullscreen(false) path described in the issue, then trace how the dialog fragment determines its height. The change is complete when a non-fullscreen dialog wraps its content instead of occupying the full screen while leaving the parent background visible around its edges.
