Hi @lunaleaps!, I want to take this issue

[Fannolo]

@lunaleaps Can I take this issue?

Edit
I saw that the MR is still open and waiting for a feedback from the author, I can take his changes for the removal of the defaultProps and add the snapshot test to it

@Fannolo Sounds good with me! Please request review from me when ready!
