I tried to test in C code...

...and it works exactly as it should.

#include <gtk/gtk.h>

int
main(int argc, char *argv[])
{
    GtkWidget *windowA, *windowB, *entry;

    gtk_init(&argc, &argv);

    windowA = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_default_size(GTK_WINDOW(windowA), 300, 240);
    g_signal_connect(windowA, "destroy", G_CALLBACK(gtk_main_quit), NULL);
    entry = gtk_entry_new();
    gtk_entry_set_text(GTK_ENTRY(entry), "Window A");
    gtk_container_add(GTK_CONTAINER(windowA), entry);
    gtk_widget_show_all(windowA);

    windowB = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_default_size(GTK_WINDOW(windowB), 200, 160);
    gtk_window_set_transient_for(GTK_WINDOW(windowB), GTK_WINDOW(windowA));
    gtk_window_set_position(GTK_WINDOW(windowB), GTK_WIN_POS_CENTER_ON_PARENT);
    gtk_window_set_modal(GTK_WINDOW(windowB), TRUE);
    entry = gtk_entry_new();
    gtk_entry_set_text(GTK_ENTRY(entry), "Window B");
    gtk_container_add(GTK_CONTAINER(windowB), entry);
    gtk_widget_show_all(windowB);

    gtk_main();

    return 0;
}
