Description

When chaining into an assertion using Which the failure message can be confusing, when the inner assertion fails, as the determined caller identity is from the outer assertion.

Complete minimal example reproducing the issue

var languages = new[] { "C#" };

languages.Should().ContainSingle()
    .Which.Should().EndWith("script");

Expected behavior:

Some nice message about "C#" not ending with "script".

Actual behavior:

Expected languages to end with "script", but "C#" is too short.
