Quick feedback on latest library update

[JohnPixle]

@lushkant Library is looking great, both in editor and admin, great work 👍🏻

Three little things until we reach perfection:

• [x] The PRO label is being shown behind the overlay

• [x] I accidentally discovered that when you hover over the pattern name, the overlay disappears, can we fix this?

• [x] In the editor, where our library popup is full-screen there is a slight border radius (3px) on the edges. Can we remove that please?

Its this class:

.dialog-widget-content {
    border-radius: 3px;
}
