bug in indentation checking when nesting objects and sealed classes

[kenyee]

Expected Behavior

This should be properly formatted:

sealed class T(val name: String) {
    sealed class C(
        name: String,
        val something: String,
    ) : T(name) {
        object Black : C(
            name = "black",
            something = "else",
        )
    }
}

Observed Behavior

It complains that lines 7-9 (starting from name="black") should be indented 4 more spaces:

/tmp/bug1.txt:7:1: Unexpected indentation (12) (should be 16) (standard:indent)
/tmp/bug1.txt:8:1: Unexpected indentation (12) (should be 16) (standard:indent)
/tmp/bug1.txt:9:1: Unexpected indentation (8) (should be 12) (standard:indent)

Steps to Reproduce

Copy first snippet into /tmp/bug.txt
Run ktlint 1.0.0 on it:

ktlint /tmp/bug.txt

Your Environment

• Version of ktlint used: 1.0.0
• Relevant parts of the .editorconfig settings
• indent_style = space
• Name and version (or code for custom task) of integration used (Gradle plugin, Maven plugin, command line, custom Gradle task): command line
• Version of Gradle used (if applicable): N.A.
• Operating System and version: OSX

This is indeed a regression bug in 1.0 release.

The problem can be reproduced with a somewhat simpler example:

class Foo(
    foo: String,
) {
    object Bar : Baz(
        baz = "baz",
        bar = "bar",
    )
}
