Despite adding .zip to file Attachment component zip files are uploading but at submission of the form it says zip not supported

AEM: 6.5.12
I have added .zip extension to File attachment component and now it lets me upload zip file.
But as soon as I click on submit button an alert pops up saying that the file is not supported.

I didn't test this earlier but seems like zip format is not supported with the Adaptive Form file attachment component.

I tried different options[0] and none of those worked for me.

Supported MIME types are listed here- https://experienceleague.adobe.com/docs/experience-manager-65/forms/getting-started/introduction-for...

[0] - 

application/zip
application/x-7z-compressed

Thanks @Pulkit_Jain_ for clarification.

One more thing, @Pulkit_Jain_ 
Does this happen, when we click on OK on the alert which says the file is not supported and submit the form again then it submits.?? 
Update: Don't bother, submitting again was successful because the attachment was deleted afterwards.

@Vinit_Pillai  due to security concerns zip is not supported. However, you can create a custom component for this similar to aem component design.
