[ttml2] Does showBackground="always" apply outside a region's begin and end times?

nigelmegitt has just created a new issue for https://github.com/w3c/ttml2:

== Does showBackground="always" apply outside a region's begin and end times? ==
The following recently was raised in face to face discussions. In an example like:

```xml
...
<region xml:id="r1" tts:showBackground="always" tts:backgroundColor="red" 
        tts:position="..." tts:extent="..." 
        begin="10s" end="20s"/>
...
```

does the red background show only during 10s to 20s or also at other times?
