Description
### Description of the bug
This bug was discovered while refactoring the code for reading and navigating the process and is a hypothetical bug of sorts.
Given this process
```mermaid
stateDiagram
direction LR
state fork <>
[*] --> Data
Data --> fork
fork --> Confirmation: if ammount >= 100
fork --> [*]: if ammount < 100
Confirmation --> [*]
```
If the flow from Data to the exclusiveGateway has flowtype set this will always be chosen regardless og what flowtype the sequence flow out of the gateway has.
### Steps To Reproduce
Create an application with a process where flows on either side of a gateway has different flowtypes.
Write custom code for both flowtypes and run the application
### Additional Information
Not sure if this will be fixed as having state changing logic tied to sequenceflows in BPMN seems like a mistake. ServiceTasks would be a much better fit IMO
Creating the issue to keep track of the bug if discovered in the wild

Research direction
The issue names no files or tests; start with the described process and custom code for different flowtypes on either side of a gateway. Done is not fully specified: the report tracks possible behavior and questions whether sequence-flow state changes should be fixed or moved to ServiceTasks.
