[BUG] Elastic.Serilog.Sinks usage triggers OperationCanceledException every few seconds

[rh101]

ECS integration/library project(s) (e.g. Elastic.CommonSchema.Serilog):

Elastic.Serilog.Sinks

ECS schema version (e.g. 1.4.0):

ECS .NET assembly version (e.g. 1.4.2):
8.12.3

Elasticsearch version (if applicable):
8.17.0

.NET framework / OS:
.NET 9 / Windows 10

Description of the problem, including expected versus actual behavior:

On running the project, the follow exception is thrown every few seconds:

Exception thrown: 'System.OperationCanceledException' in System.Private.CoreLib.dll: 'The operation was canceled.'

If the Elasticsearch serilog sink is not used, then that exception is not triggered.

The call stack shows the following:

Steps to reproduce:

Visual Studio 2022 project at https://github.com/rh101/SerilogESTest

Use docker compose to run the project.
