    Revert "about dialog: Set a max-content-height on credits"
    
    This reverts commit 6af5033386b60bdf71cc21d99d579c2a8c389880.
    
    Scrolled window behavior of propagating child natural sizes
    has now been made optional, so there is no need to work around
    this by setting a hard coded maximum content height anymore.
