Loading indicator in pick from WP Media lib does not disappear when 1 match in search

[develric]

Expected behavior

When picking from the WP Media lib and using the search feature, I expect the bottom loading indicator to disappear after matching images are loaded.

Actual behavior

When picking from the WP Media lib and using the search feature, the bottom loading indicator does not disappear after matching images are loaded, when only 1 image matches.

Steps to reproduce the behavior

• In GB place an Image block
• Add image from WP Media Library
• Be sure to have only one image matching the search (for example I have only 1 image matching the cat search here below

- Notice the bottom loading indicator does not disappear after the 1 matching image is loaded
