Wrong indentation text in functions with expression body

[aktsay6]

  private fun ASTNode.extractLinesFromBlock(type: IElementType): List<String>? =
              treeParent
              .getFirstChildWithType(type)
              ?.text
              ?.trim('{', '}')
              ?.split("\n")
              ?.filter { it.isNotBlank() }
              ?.map { it.trim() }
              ?.toList()

If there are 12 spaces before method call, rule requires 16 spaces. If there are 16 spaces, rule requires 12.

I believe, correct way would be

  private fun ASTNode.extractLinesFromBlock(type: IElementType): List<String>? =
          treeParent
              .getFirstChildWithType(type)
              ?.text
              ?.trim('{', '}')
              ?.split("\n")
              ?.filter { it.isNotBlank() }
              ?.map { it.trim() }
              ?.toList()

i.e. after = there are 8 spaces and each dot-qualified call is indented by 4 spaces more. Does it not fix like this or is there an error with warning text?

Actually it's fine, I just didn't see the correct indentation
