Calling services.wysiwyg.fromAnnotatedXHTML from jobMacro crash with npe

Adding one observation:

In DefaultTemporaryAttachmentSessionsManager, the session retrieved from the XWikiRequest is null, despite the fact that the current XWikiRequest is cloned by the JobMacro, by XWikiContextCopier, in the following statement:

clonedXWikiContext.setRequest(this.xwikiRequestCloner.copy(originalXWikiContext.getRequest()));

However, when setting a breakpoint on XWikiContextCopier#L81 and evaluating expressions originalXWikiContext.getRequest().getSession() and clonedXWikiContext.getRequest().getSession(), I noticed that the former returns an object as expected, but not the latter. Which means the JobMacro does not copy the session, which could be a bug of the JobMacro.
