DMN Editors quick menu adds node beyond canvas northern boundary

Summary
When user creates a new node on top of the canvas and uses quick menu to add new nodes. The nodes are added beyond the visible area of canvas (above the node) and user is unable to access them.
The issue is also that the visible area of canvas is not extended until the initial node is moved on canvas.
User is also unable to move the node in this area using click&drag, only when the mouse pointer reaches the actual canvas (below the - - - - - -  line) the drag works and follows mouse pointer.

See attachment video for details.

Acceptance criteria
New nodes should be added into area where user can work with them
Editor should not add new nodes into inaccessible area of canvas.
if node is added above into this area, user can click & drag the node without issues.
