The isNewMsg property only appears in the latest unread message.

Description

I have implemented the following function:

window.WAPI.list = async function () {
  const options = {
    onlyWithUnreadMessage: true
  };

  const chats = await WPP.chat.list(options);
  let messagesResult = [];

  if (chats) {
    try {
      for (var i = 0; i < chats.length; i++) {
        if (chats[i].unreadCount > 0) { // Verifique se msgs existe
          let msgs = await WPP.chat.getMessages(chats[i].__x_id._serialized, {count: -1, onlyUnread: true});
          for (var j = 0; j < msgs.length; j++) {   
            console.log("msg:", JSON.stringify(msgs[j]));         
            if (msgs[j].__x_isNewMsg === true) {                    
              messagesResult.push(msgs[j]);
            }
          }
        }
      }
      console.log(JSON.stringify(messagesResult));
      //SetConsoleMessage("getList", JSON.stringify(messagesResult));
    } catch (e) {
      console.log('Erro:'.concat(e));
    }
  } else {
    console.log('ERRO');
  }
};

Previously, in the version of wa-js v2.24.7 with WhatsApp 2.2333.11, if I sent the messages:
1
2
3

using my implementation:

if (msgs[j].__x_type === 'chat' && msgs[j].__x_isNewMsg === true) {                    
    messagesResult.push(msgs[j]);
}

All three messages were added within the messagesResult.push(msgs[j]);.

However, in the latest versions of wa-js (v2.25.0) and WhatsApp Web (2.2335.9), only the message "3" retains the isNewMsg property, and the messages "1" and "2" do not have this property anymore.

But in my test case, messages 1 and 2 should have isNewMsg = true because they were sent simultaneously along with message 3.

Environment

• WhatsApp version: 2.2336.8
• WA-JS version(s): v2.25.0
• Browser: Chrome 110.0.5481.179 / Chromium 110.0.31.0
• OS: Windows 10
• MultiDevice (BETA): yes

@daviladanielc , please, don't use __x_ attributes, they are non standard

[marcelo386]

window.WAPI.list = async function () {
const options = {
onlyWithUnreadMessage: true
};

const chats = await WPP.chat.list(options);
let messagesResult = [];

if (chats) {
try {
for (var i = 0; i < chats.length; i++) {
if (chats[i].unreadCount > 0) { // Verifique se msgs existe
let msgs = await WPP.chat.getMessages(chats[i].id._serialized, {count: -1, onlyUnread: true});
for (var j = 0; j < msgs.length; j++) {

        if (msgs[j].isNewMsg === true) {                    
          messagesResult.push(msgs[j]);
        }
      }
    }
  }
  //console.log(JSON.stringify(messagesResult));
  SetConsoleMessage("getList", JSON.stringify(messagesResult));
} catch (e) {
  console.log('Erro:'.concat(e));
}

} else {
console.log('ERRO');
}
};

modified the attribute _x even so it is not returning all messages pending reading, it only lists the last message
