SPUC SK Effects: Keyboard not activated when text input selected more than once

Steps to reproduce:

1. Use the following snippet to create a simple callout
<fx:Declarations>
<s:Callout id="callout" contentBackgroundAppearance="none" verticalPosition="after">
<s:VGroup width="100%" height="100%" gap="8">
<s:VGroup width="100%" horizontalAlign="center"
paddingTop="20" gap="20">
<s:Label text="This is a custom alert box"/>
<s:Button label="OK" click="callout.close();"/>
</s:VGroup>
<s:TextInput width="100%"/>
<s:Button label="Close" click="callout.close()" width="100%"/>
</s:VGroup>
</s:Callout>

</fx:Declarations>
<s:VGroup top="10" left="10">
<s:TextInput id="textInput" prompt="Open Callout"
focusIn="callout.open(textInput)"
softKeyboardActivate="callout.open(textInput)"/>
</s:VGroup>
2. Select the text input "Open Callout"
3. Softkeyboard gets activated and pop up opens as expected.
4. Set focus on the same text input again.

Actual Results:
1. Softkeyboard closes - should remain activated.
2. Click on Text Input again - softkeyboard does not open up.

Expected Results:
Softkeyboard should get/remain activated as long as the focus is on text input.
