Fade animations on shadows do not work on WindowClose event for TextBoxScrollup controls, it may also be a problem on different events.

h4. Steps to Reproduce
1. Create a textboxscrollup control with noticeable delay on windowclose e.g.

<control>
<description>Plot value</description>
<type>textboxscrollup</type>
<id>1</id>
<posX>39</posX>
<posY>384</posY>
<width>299</width>
<height>168</height>
<label>#plot</label>
<font>font11</font>
<textcolor>FFFFFFFF</textcolor>
<visible>facadeview.list + control.hasfocus(50)</visible>
<animation effect="slide" time="150" start="-300,0" reversible="false">visible</animation>
<animation effect="fade" time="450">WindowOpen</animation>
<animation effect="fade" time="1500">WindowClose</animation>
</control>

2. Open window
3. Exit window

Result: Shadow text in textboxscrollup control does not fade on window exit.

h4. Additional Information
A fix was made earlier to textbox controls, most likely the same fix should be applied to textboxscrollup.
