Qt *.ui files designer does not show resources of sibling subprojects.

Qt *.ui files designer does not show resources of sibling subprojects.

The example of a project structure:

For example when I open MainWindow.ui in User Interface designer, the "Select Resource" dialog does not have assess to the resources of sibling subproject Sub2.pro

And all icons of buttons and actions which uses resources located in siblings projects are empty.

But I can add icon in source code:

#include "MainWindow.h"
#include "ui_MainWindow.h"

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    ui->toolButton_2->setIcon(QIcon(":/icons/Add.svg"));
}

MainWindow::~MainWindow()
{
    delete ui;
}

The bug appeared after update from 4.9.2 to 4.10.0
