Description

As the title suggests, the OP of an issue is not affected. Only replies have to at least have a body for changes to attachments to be applied. Note that the initial upload succeeds without a body. You just cannot change it without changing the body.

See https://try.gitea.io/CL-Jeremy/Test/issues/1#issuecomment-31206, this also happens when there is already some content in body:

Newly uploaded files will not be reflected after refreshing until the body is modified (cf. https://try.gitea.io/CL-Jeremy/Test/issues/1#issuecomment-31207):
