Report cuts off dataflows in the diagram

[jgadsden]

Describe the bug:

when 2.3.0 is used to create a report from a model model created in 2.2.0, the bottom is cut off:

Same thing happens when a PDF report is created

This was not the case in 2.2.0:

Expected behaviour:

The report shows the complete / full diagram

Environment:

• Version: 2.3.0 (and not in 2.2.0)
• Platform: Web App
• OS: any
• Browser: any of chrome, firefox, safari

To Reproduce:

1. create a new threat model diagram
2. add two nodes to the diagram - any of Actor, Data Store or Process
3. connect a dataflow between the two nodes
4. make the data flow go beyond the bottom edges of the nodes
5. create a report - either PDF or HTML

Workaround:

Ensure that the dataflow is above the lowest line of the diagram nodes
