Debug view threw Unable to cast object of type 'Microsoft.EntityFrameworkCore.Metadata.RuntimeNavigation' to type 'Microsoft.EntityFrameworkCore.Infrastructure.AnnotatableBase'

We have a deep integration into ef core. As a safety measure with each update we compare the generated ef-model using the debug string.

With ef core 9 annotations are no longer included (using sqlite). For example the MaxLength attribute outputs the following error:
Debug view threw Unable to cast object of type 'Microsoft.EntityFrameworkCore.Metadata.RuntimeNavigation' to type 'Microsoft.EntityFrameworkCore.Infrastructure.AnnotatableBase'.. Please report this at https://github.com/dotnet/efcore
