How to ignore broken image links

[t-hamano]

Description

When I retrieved the images via the REST API, I noticed that some of them were inaccessible due to a 410 error. WordPress block editor gets the image list to be inserted into the content via the endpoint, but some images aren't inserted due to the HTTP error above.

Reproduction

• Access https://playground.wordpress.net/ to start the WordPress instant environment
• Go to the Dashboard > Create a new post > Open the main inserter > Click the Media tab > Click the Openverse menu
• Search images by "mountain"
• You should see that some images have no preview.
• Click them. Browser console outputs the 410 (Gone) error and the image isn't inserted.

Request example:

https://api.openverse.org/v1/images/?page_size=20&q=mountain&mature=false&excluded_source=flickr%2Cinaturalist%2Cwikimedia&license=pdm%2Ccc0

Additional context

We may be able to filter out the broken images on the client side, but I'd appreciate it if I could know why the broken images are included in the first place and if there is an option to filter them out.
