Media: Editor freezes when saving a post with several images

[fluiddot]

Description

In a post/page that contains several images (more than 10 items), the editor becomes temporarily unresponsive upon saving. This seems an error specific to the iOS platform, as on Android the unresponsiveness is not experienced.

Step-by-step reproduction instructions

1. Open the iOS app.
2. Create a new post.
3. Add a Gallery block.
4. Add 15 images from the device.
5. Save the post.
6. Observe that the editor freezes for several seconds until navigating to the posts/pages list.
7. Open the same post.
8. Add a Paragraph block with some text.
9. Save the post.
10. Observe that the editor freezes for several seconds again.

Expected behaviour

The editor should be closed right after saving the post.

Actual behaviour

The editor freezes when saving a post becoming temporarily unresponsive.

This issue is still happening in version 24.4. It seems to be caused by the same culprit shared in wordpress-mobile/gutenberg-mobile#6696 (comment).

Closing this issue as it should be solved in WP/JP app version 25.0 via wordpress-mobile/WordPress-iOS#22896.
