Draw Text Actor measure output values?

[mark_m]

I am using the draw text actor's measure mode to scale a shape which is the background of the text. Like the background for subtitles.
For some reason, even when there's no text input, the text width and text height have values, when I would expect them to be zero.

I can get around this using a limit-scale-value actor, but still curious as to why this is happening...

Thoughts? Explanations? Logic?
