fix: Stop preview card text overlapping images (#924)

Browse Source 
In rare occasions the preview card text could overlap the image if the
image had a portrait aspect ratio.

This seems to be due to the use of the `with(...) {}` scope function and
Kotlin's interoperability with Java setters.

Replace this with code that explicitly gets and sets the layout params
to ensure they are set correctly.
