Describe the bug
In the latest update of draw.io, the UI has changed, and BPMN diagrams no longer automatically generate corner arrows when connecting from a gateway. Previously, this behavior was in line with BPMN notation, but now users have to manually adjust the arrows, which is inconvenient and inconsistent with standard notation.

To Reproduce
Steps to reproduce the behavior:

1. Open draw.io and create a new BPMN diagram.
2. Add a gateway element.
3. Try connecting it to another element (e.g., a task or event).
4. Notice that the connection does not automatically form a cornered arrow as it used to.

Expected behavior
When connecting from a BPMN gateway, the arrow should automatically create a cornered path, as per BPMN standards.

Actual behavior
The arrow is drawn in a straight line, requiring manual adjustment.
