kltint fails for indents using 2 interfaces

[neugartf]

Hey! Not entirely sure who is wrong here, either the auto-format from IntelliJ or ktlint. Weird thing is that ktlint succeeds if i reduce it to one interface.

Expected Behavior

Ktlint shouldn't not complain about the indention. Unexpected indentation (4) (should be 8) (indent)

Observed Behavior

Ktlint fails with Unexpected indentation (4) (should be 8) (indent).

Steps to Reproduce

1. Checkout http://github.com/neugartf/ktlint-gradle
2. Set Kotlin Coding Conventions as default for the project
3. Run :samples:kotlin-gradle:ktlintMainSourceSetCheck

Your Environment

• Version of ktlint used: 0.40.0
• Name and version (or code for custom task) of integration used (Gradle plugin, Maven plugin, command line, custom Gradle task): JLLeitschuh/ktlint-gradle@10509e9
• Version of Gradle used (if applicable): gradle-6.6.1
• Operating System and version: MacOS 10.15.7
• Link to your project (if it's a public repository): https://github.com/neugartf/ktlint-gradle

I think #961 is the cause of this issue.
