Browser cache for attachement is not invalidated on rollback

Reproductions steps

1. create a page
2. upload attachment a.txt with content "Version 1"
3. check the content of the attachment (e.g., http://localhost:8080/xwiki/bin/download/AttachmentTest4/WebHome/a.txt?rev=1.1) this is "Version 1"
4. delete a.txt
5. upload attachment a.txt with content "Version 2"
6. check the content of the attachment (e.g., http://localhost:8080/xwiki/bin/download/AttachmentTest4/WebHome/a.txt?rev=1.1) this is "Version 2"
7. rollback to the document revision where a.txt with content "Version 1" was just uploaded
8. check the content of the attachment (e.g., http://localhost:8080/xwiki/bin/download/AttachmentTest4/WebHome/a.txt?rev=1.1)

Expected

The content of the attachment is "Version 1"

Actual

The content of the attachment is "Version 2"

Explanations

With a hard refresh (Ctrl+Maj+R), the content of the attachment is correctly "Version 1", meaning that there is a browser cache invalidation issue.
But, we probably have a mechanism to invalidate the cache as other with attachment content check would already fail right after the check of the attachment content after the second upload.
