QML inline components from other files are not recognized in the editor

In Qt Creator's QML code editor, referencing inline components defined in another QML file does not work properly. It seems that they are not recognized at all. Steps to reproduce:

1. New project > Application (Qt) > Qt Quick Application
2. Build system - qmake (probably not important, but that's what I use)
3. All other options default
4. New File > Qt > QML File (Qt Quick 2) > Images.qml > Add to qml.qrc
Prefix: /
5. Images.qml contents:

import QtQuick 2.15

Item {
	component LabeledImage: Column {
		property alias source: image.source
		property alias caption: text.text
		Image {
			id: image
			width: 50
			height: 50
		}
		Text {
			id: text
			font.bold: true
		}
	}
}

6. Go back to main.qml and try using Images.LabeledImage

import QtQuick 2.15
import QtQuick.Window 2.15

Window {
	Images.LabeledImage {
		caption: "Caption"
	}

	width: 640
	height: 480
	visible: true
	title: qsTr("Hello World")
}

Expected Behavior: Images.LabeledImage is recognized and autocompletion for its properties is available.
Observed Behavior: Qt Creator shows an error "Unknown Component. (M300)", and autocompletion is not available. Building and running the project works as expected and the LabeledImage is shown, so the issue is just in the code editor.

Inline components defined in the same file are recognized and work without issues.

Using Qt Creator 8.0.2.
