external_reply.origin.sender_user does not show the correct user (replying to a forward)

[wiz0u]

When replying to a message from another chat which was a forward, the sender_user seems to be filled with information from the initially forwarded user, rather than information about the message sender in the other chat:

in the below example, replying to https://t.me/iamnotstalin2Chat/665,
we would expect sender_user to identify Андрей rather than НЕ СТАЛИН

maybe ExternalReplyInfo structure should have both a origin (or from?) field AND a forward_origin field, to differenciate the message sender and the forwarded user

[levlam]

This is intended. MessageOrigin always represents the initial sender of the message both in forwards and ExternalReplyInfo.

Actual source of the forward is available only in Saved Messages, the Replies chat, which aren't relevant for bots.

If you want Telegram to provide the latter for all chats, then you need to create a card at https://suggestions.telegram.org, unless one already exists.

[wiz0u]

why not add a from (User) field to ExternalReplyInfo ?

seeing the screenshot above (taken in chat with bot), one would expect that information to be available (to bots too)

[levlam]

why not add a from (User) field to ExternalReplyInfo ?

Because there is no such information as I explained.

Is it Telegram Desktop? You must restart it to see the actual message.

Is it Telegram Desktop? You must restart it to see the actual message.

yes. I just restarted Telegram Desktop and went straight to my chat with @JsonDumpBot,
the message still appeared the same with all information about real sender.

note: I'm not even a member of https://t.me/iamnotstalin2Chat so Telegram Desktop did not fetch the origin message from my chats.

[wiz0u]

I just opened Telegram Android, the message appear as you said, with only НЕ СТАЛИН

[levlam]

I just restarted Telegram Desktop and went straight to my chat with @JsonDumpBot,

You didn't restart it. You closed the window and minimized the app to tray. You can close it from there.

[wiz0u]

Trust me, i closed it. (retried again now, same, even checked Process Explorer )
I disabled minimize to tray

[levlam]

There is no way Telegram Desktop can keep this state of the message if closed.

[wiz0u]

🤷🏻‍♂️ maybe it auto-fetches the replied message to get & display more info?
https://t.me/iamnotstalin2Chat is a public chat after all

[levlam]

It can't. The message contains no information about the place from which it was forwarded last time.
