Elastic.Apm for .net breaks traces

[incloudss]

Describe the bug
Elastic.Apm interferes with default .net diagnostic activity behaviour and breaks traces. Versions checked: 1.23.0, 1.24.0, 1.25.0
Here is the jaeger visualization of good trace (using OpenTelemetry), and the broken one by Elastic.Apm:

Good:

Broken:

To Reproduce

1. Download repro repository:
   https://github.com/incloudss/elasticapmbug/tree/main
2. Run both services (visual studio F5 for example)
3. Call http://localhost:5151/upper

Repository is configured to push telemetry data to jaeger.

The repository by default has Elastic.Apm enabled that breaks traces. If you comment out the line app.UseElasticApm(app.Configuration); for both Program.cs, the traces will be correct.

Expected behavior
To not break traces.
