Issues to attach GIF files on the new editor

Summary

When trying to attach a GIF to a blog post (or meeting notes), the upload will finish loading and won't show the image's preview. After publishing the page, it's also not possible to resize the GIF file.

Environment

• Confluence cloud
• New editor (meeting notes, blog post)

Steps to Reproduce

1. Create a new blog post
2. Click on the File & images button, select a GIF file and then open it;

Expected Results

• The image would be uploaded successfully and a preview would be shown
• It should be the same size as the original file

Actual Results

• The upload ends but the preview is not shown;
• The GIF file is very small and not resizable.

Notes

I was able to reproduce it with a big file (10MB)

Workaround

No known workaround so far.
