Instant Run doesn't work with proguard

Question

I am researching the "instant run" feature in Android Studio. But it looks like it doesn't work with proguard. Is there anybody know why and how to get them work together?

My environment: Android Studio 2.0 Beta 4

My top level build.gradle

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-beta4'
    }
}

allprojects {
    repositories {
        maven { url "http://dl.bintray.com/populov/maven" }
        mavenCentral()
        jcenter()
    }
}

The build.gradle for module:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        minSdkVersion 17
        targetSdkVersion 23
    }
    buildTypes {
        debug {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:23.1.1'
}

I can see some following "instatn run" tasks in gradle console with the above setting. And there is a yellow thunderbolt appear with the run button.

:TestIR:transformClassesWithInstantRunVerifierForDebug
:TestIR:transformClassesWithInstantRunForDebug
:TestIR:transformClasses_enhancedWithInstant+reloadDexForDebug
:TestIR:generateDebugInstantRunAppInfo
:TestIR:transformClassesWithInstantRunSlicerForDebug

Dexing C:\git\android\TestIR\build\intermediates\transforms\instantRunSlicer\debug\folders\1\5\slice_5 took 321
Dexing C:\git\android\TestIR\build\intermediates\transforms\instantRunSlicer\debug\folders\1\5\slice_3 took 456

But if I set "minifyEnabled" to true, there is no "instant run" task in Gradle console any more, either the yellow thunderbolt button.

Is there anyway to get them work together?

According to this official Android developer page, Android Studio disables ProGuard when using Instant Run.
