Copy/paste of pictures fail since 16.3.0

Good day everyone!

I’m facing an issue since I updated to XWiki 16.3 (Docker image).

Collaborative editing is lightning fast but when I copy / paste a picture, it displays a black square and, checking the source of the page, it gives me :

[[image:data:image/gif;base64,R0lGODlhDgAOAIAAAAAAAP///yH5BAAAAAAALAAAAAAOAA4AAAIMhI+py+0Po5y02qsKADs=]]

The picture was uploaded (in the attachments at the bottom) and I have the same error when I switch to “not collaborative editing” (xwiki-realtime OFF in CKEditor plugins).

Hopefully I’ll find the solution soon!

Ouch, I confirm that I could reproduce and I’ve created Loading...

Sorry about that, we’re going to fix it real soon.

Thanks for the reactivity (as usual :muscle:), as the picture is uploaded, it’s quite easy to update the black square with it.
