Proposal

Please re-state the problem that we are trying to solve in this issue.

• Image MD - LHN preview shows "Attachment" instead of "Text [Attachment]" after reopening chat

What is the root cause of that problem?

• In offline mode, the last message is displayed as "text (image of ${image-name})". It is because the last message text is from here, where we use parser.htmlToText(htmlForNewComment), that will replace image tag with (image of $4)
• In online mode, BE return [Attachment] instead of text [Attachment]

What changes do you think we should make in order to solve the problem?

• We need to update this to:

                replacement: '[Attachment]',

• Then, BE need to change based on it for consistency

What alternative solutions did you explore? (Optional)

• NA

Looks like inline image markdown is not live on production yet, so it's a new feature:

Ah yes, this is the PR that introduced the new functionality, removing the deploy blocker label
