Removing drop shadow for transparent In App Messages

[emawby]

Description

One Line Summary

Removing the drop shadow for elements in In App Messages with transparent backgrounds.

Details

This dropshadow only appeared when the background of the IAM was transparent. This is not an intentional visual feature so we are removing it. The shadow was added in the initial implementation of IAMs and was likely never noticed since it only appears for transparent backgrounds.

Motivation

Bug noticed when implementing transparent IAM backgrounds.

Scope

transparent background iOS IAMs
