Summary
The fields requested in announcing a new issue should use inline help information to explain to users what is being requested for each field. For example, currently full URLs are not allowed in the "Page title of the issue" field (T180984). Noting this inline would be helpful to publishers not aware of this limitation.
Description
Both fields on the Announce interface should use the "FieldLayout aligned top with help" properties as described in the OOjs UI documentation (demo)
