A message with attachments showed a paperclip and nothing else, so the
only way to reach a file was to open the message, scroll to the bottom
and find it. The list rows never had the information to do better:
EMAIL_LIST_PROPERTIES asked for hasAttachment, a boolean.
Request attachments alongside it and render the files as chips under the
preview, each one opening that file directly. Chips honour the existing
mailAttachmentAction setting, so they preview or download exactly as the
viewer's attachment list does.
Inline parts are filtered out. A single Outlook message routinely carries
half a dozen cid: signature spacers of under 200 bytes; chipping those
would bury the one file the reader actually wants. Only parts that are
neither inline nor cid-referenced, and that carry a filename, are shown —
two at a time, with the remainder collapsed into a count.
Downloads resolve the blob source from the row's own message rather than
the selected one, so they stay correct in the unified inbox where each
row can belong to a different account.
