Flowchart: line from rhombus to subgraph uses bounding box of rhombus instead of actual border

[rene-martin-pbm-healthcare]

Description

When trying to draw a flowchart diagram with a rhombus and a subgraph, lines from the rhombus to the subgraph seem to behave different than lines from the rhombus to other same-level-nodes. Lines to such nodes start at the actual border of the rhombus, but lines to subgraphs seem to always start at the bounding box of the rhombus.

Steps to reproduce

Use this example:

graph LR
    subgraph B
        direction LR
        B_1
    end
    A{A} --- C
    A --- B
