Transclusions always work that way. The expansion of {{:Jurassic Park}} isn't even done inside Scribunto, the parser does that before Scribunto even sees it.

To be able to do something like what you're asking, you'd need:

• Allowing access to the unparsed wikitext of parameters (which would need a change to the MediaWiki-Parser to make it possible, then a change in Scribunto to make use of it)
• A variant of frame:preprocess() that ignores side effects when doing the preprocessing.
• The module to be rewritten to take advantage of this.

Or if you're willing to change the way you pass the parameter to #invoke, you could get away with just the second bullet. If you want those first two things, file separate feature request tasks for them.
