@bsclifton so if I understand correctly this PR, we only have this prop here so that we trigger re-render? If this is the case, can you please add a small comment about it so that someone will not remove it (it's not used anywhere).

[bsclifton]

@NejcZdovc that is correct. Will update with comment 😄
