CSS Media Query for large screens missing

Hello

I stumbled on your plugin used by a customer.
There is a problem with the CSS for large screens.

The file https://app.mailjet.com/statics/css/w-iframe-less.css has on line 79 this media query

@media (min-width: 769px) and (max-width: 1199px) {
    body form.mj-form .mj-embedded.mj-vertical {
    width: 100% !important;
    padding-bottom: 15px !important;
}
}

This makes that on screens from 1200px this CSS is lost and the form falls back to this basic setting without any width anymore (line 67):

@media (min-width: 769px) {
body form.mj-form .mj-embedded.mj-embed-shadow {
    padding: 20px !important;
    background-color: transparent !important;
    box-shadow: none !important;
}
}

Also, I think it is better to embed this CSS in the plugin itself, instead of making this an external file.

Could you have a look on this and fix? Thx a lot!
