feat(enh): typeguard cloned elements to remove warnings

[hyochan]

Description

React may throw a warning related to issue #251 when undefined style props are provided to its elements. While this is generally not an issue in the real world, our customers may be annoyed by the warning message. In this commit, we have implemented a typeguard to address this issue when styling cloned elements.

Test Plan

Pass Image to startElement or endElement in [Button] then you will not see the warning message.
