Sub-graph direction in flowchart-elk cannot change direction

Description

Sub-graph direction in flowchart-elk cannot change direction

Steps to reproduce

First, I set the layout of subgraphs from left to right through flowchart-elk LR, and then I set 3 subgraphs, and the direction of each subgraph is from top to bottom. As a result, if the direction setting of subgraphs is not effective, it is from left to right. This is different from flowchart's default rendering method. I have worked hard to help you read it and wait for your reply. Thank you
