Shared Element transition bug from TextView to EditText

问题

I am trying to do an Android Shared Transtion between a TextView and a EditText´ but when showing the resulting Activity the text in theEditViewhave been shifted up. See attached pictures. Also, clicking on theEditView` after the transition will restore the text to the correct position.

First clicking any row in RecylcerView:

The cell view, the date TextEdit and the Name TextEdit are shared to the next activity. The cell background is transitioned into the toolbar.

Start activity cell layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/adapter_actionlist"

              android:layout_width="match_parent"
              android:layout_height="wrap_content"
