Instant run does not work with layout-21

Question

Here is a case that instant run in AS is not working:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    toolbar.setElevation(visible ? getResources().getDimension(R.dimen.elevation_toolbar) : 0);
} else {
    View toolbarShadow = findViewById(R.id.toolbar_shadow);
    toolbarShadow.setVisibility(visible ? View.VISIBLE : View.GONE);
}

The view in layout has the R.id.toolbar_shadow. All good.

However if you have a view in layout-21 which does not contain the R.id.toolbar_shadow then when you compile the app to an e.g. Api 23 device gradle will fail with :

Error:(1046, 42) error: cannot find symbol variable toolbar_shadow

Any ideas to solve this?

Update: as requested the layouts:

res/layout/actionbar.xml:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    ... >

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        ... />

    <View
        android:id="@+id/toolbar_shadow"
        ... />

</LinearLayout>

res/layout-21/actionbar.xml:

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar"
            ... />

Yes : without instant run is fine. With instant run it fails with the above error. — Diolor, May 06 '16 at 16:48

Ok found the solution added manually the missing id in the resourses:

<!--To make Instant Run work if these ids are not in 21+-->
<item name="toolbar_shadow" type="id"/>

This is strange though, possibly file a bug report? – CaptJak May 06 '16 at 16:51
