Some specific image not uploading correctly on 6.8.2

[krisz768]

If i upload this image o the admin it gives an error after a while.

If i use "wp_insert_attachment_from_url", it stops at the call and does not give an error or anything.

On an older version it was fine (6.7)

While debugging, I found out this happens after #36477 ticket got merged

In more detail, this PR code causes the request to timeout ​https://github.com/WordPress/wordpress-develop/pull/7556/files

• If we revert the PR code, the file upload works fine.

Can you please confirm if this issue is happening with only this specific image or with other large PNG files as well? I am wondering if it might be related to the file size or the way the image is encoded. Also, since it was working in 6.7, is there a recommended workaround until a patch is available?

Thanks!

@SergeyBiryukov @proxycoder23 I've tested with the latest code after [63448] was merged, and it has fixed the issue.
