vue-advanced-chat: bug: didn't load more messages when messagesLoaded once set to true

	fetchMessage(data) {
		console.log(data)
		if (data.options) {
			this.messagesLoaded = false
			this.messages = []
			data.room.unreadCount = 0
			this.selectedRoom = data.room
			db.set("rooms", this.rooms).write()
			const muted = (data.room.roomId < 0 && this.muteAllGroups && !data.room.unmute) ||
				(data.room.roomId < 0 && !this.muteAllGroups && data.room.mute) ||
				(data.room.roomId > 0 && data.room.mute)
			this.menuActions.find(e => e.name == "mute").title = muted ? "Unmute Chat" : "Mute Chat"
			this.menuActions.find(e => e.name == "pin").title = data.room.index ? "Unpin Chat" : "Pin Chat"
		}
		const msgs2add = db.get("messages." + data.room.roomId)
			.dropRightWhile(e => this.messages.includes(e))
			.takeRight(10).value()
		if (msgs2add.length)
			this.messages = [...msgs2add, ...this.messages]
		else
			this.messagesLoaded = true
	},

Once I scrolled to the very top of a conversation, then switch to another room, then switch back. It just loaded the last 10 messages and doesn’t load more messages any more, Even I switch to other room which have more than 10 messages
