SmugMug Block Displays a White Box when Embedding Gallery Links

[ash1eygrace]

Description

When adding a SmugMug gallery link into the WordPress SmugMug block, it results in a white box rather than displaying the gallery.

Step-by-step reproduction instructions

1. Create a Gallery on SmugMug.
2. Click the Share button to Copy the Gallery Link.
3. Add a /smugmug block to your WordPress page or post.
4. Paste the gallery link into the block.
5. Save and preview the live page.

Expected Result:

It's unclear if the block supports galleries or slideshows. If they are supported, I expect the gallery to appear, but if they aren't, I expect the block to provide a warning in the Editor indicating that only individual image or video links are accepted.

Actual Result:

A white box appears instead of displaying the gallery.

Workaround

You can embed a SmugMug slideshow using and HTML Block and the provided iframe from SmugMug.
