FP of LOCAL_VARIABLE_EARLY_DECLARATION with other variables and a loop

Describe the bug

    private fun collectAllExtensionFunctions(node: ASTNode): SimilarSignatures {
        val extensionFunctionList = node.findAllNodesWithSpecificType(FUN).filter { it.hasChildOfType(TYPE_REFERENCE) && it.hasChildOfType(DOT) }
        val distinctFunctionSignatures = mutableMapOf<FunctionSignature, ASTNode>()  // maps function signatures on node it is used by
        val extensionFunctionsPairs = mutableListOf<Pair<ExtensionFunction, ExtensionFunction>>()  // pairs extension functions with same signature

        extensionFunctionList.forEach { func ->
            val functionName = (func.psi as KtNamedFunction).name!!
            // List<String> is used to show param names in warning
            val params = (func.getFirstChildWithType(VALUE_PARAMETER_LIST)!!.psi as KtParameterList).parameters.map { it.name!! }
            val returnType = func.findChildAfter(COLON, TYPE_REFERENCE)?.text
            val className = func.findChildBefore(DOT, TYPE_REFERENCE)!!.text
            val signature = FunctionSignature(functionName, params, returnType)

            if (distinctFunctionSignatures.contains(signature)) {
                val secondFuncClassName = distinctFunctionSignatures[signature]!!.findChildBefore(DOT, TYPE_REFERENCE)!!.text
                extensionFunctionsPairs.add(Pair(
                    ExtensionFunction(secondFuncClassName, signature, distinctFunctionSignatures[signature]!!),
                    ExtensionFunction(className, signature, func)))
            } else {
                distinctFunctionSignatures[signature] = func
            }
        }

        return extensionFunctionsPairs
    }

=>

ExtensionFunctionsSameNameRule.kt:82:9: [LOCAL_VARIABLE_EARLY_DECLARATION] local variables should be declared close to the line where they are first used: <distinctFunctionSignatures> is declared on line <82> and is used for the first time on line <85>
