DisableEncoding works only for first SerializeObject-call when using same RazorLightEngine

[ChristophSol]

Hello everyone,
i am currently trying to build several strings using RazorLight and a cshtml-file:
engine.CompileRenderAsync("Assets.Embedded.R4200", layoutParameter)

layoutParameters might contain special characters like '<' or 'ö'. Using both "DisableEncoding()" function when building RazorLightEngine via RazorLightEngineBuilder or using "@(new HtmlString(Model.V02))" inside the cshtml-file works for one call only. All subsequent strings contain those special characters in encoded form (e.g. &#xDC) I am using the same RazorLightEngine for all calls.
My current workaround is to create a new RazorLightEngine for every call. Trying to change this..
I am logging "engine.Options.DisableEncoding" for every call. It is set to true.

Is it my understanding of Razor that is incomplete (this is the first time I am using it)? Is this the expected behaviour?
I do not exactly know which further information might be useful for help. I am using .net-core 3. Autofac-module is used to create a single instance of RazorLightEngine. I use this entry in my csproj-file:

ItemGroup
None Remove="Assets\Embedded*.cshtml"
EmbeddedResource Include="Assets\Embedded*.cshtml"
ItemGroup

Using
@using RazorLight
@{
DisableEncoding = true;
}
as described in readme https://github.com/toddams/RazorLight#encoding
solves this issue. For me the problem is solved right now. I do not understand the different behaviour yet. However, im fine with that. One might either close this topic or wait for comments providing further information on this.
