Regression in 4.3.1: this.directions.setDestination and this.directions.setOrigin no longer populate sources.directions

[Joso997]

In version 4.2.0, calling the following:

this.directions.setDestination(this.destinationLocation);
this.directions.setOrigin([e.coords.longitude, e.coords.latitude]);

console.log(this.directions);
console.log(this.map.getStyle().sources.directions.data);

Correctly populates sources.directions with two features.

However, after upgrading to 4.3.1, this behavior has changed. The same calls no longer populate sources.directions as expected.

Expected Behavior:

• After setting the destination and origin, the sources.directions should contain two features.

Actual Behavior:

• In 4.3.1, sources.directions remains empty or does not populate as it did in 4.2.0.

Steps to Reproduce:

1. Initialize directions and map in 4.3.1.
2. Set destination using this.directions.setDestination.
3. Set origin using this.directions.setOrigin.
4. Check the contents of sources.directions using console.log(this.map.getStyle().sources.directions.data).

Workaround:

Provide any workaround you've found, or indicate none if not available.

Environment:

• Version: 4.3.1
• Browser/Device: [Add details]

Could you investigate the change between versions and provide guidance on the correct way to populate sources.directions in 4.3.1?
