Hub/Pivot App template breaks when navigated

Question

I using universal app model, Hub/Pivot App template. There's some bug with template.

When I navigate from hub.html to other html-page (created as PageControl) and go back then Hub/Pivot layout breaks! This pic clearly show you what happens: screenshot.

What I'm doing:
1. Create PageControl as it is written
2. WinJS.Navigation.navigate("/somefolder/somepage.html");

Answer 1

Problem was solved by changing class in CSS-file of page created as PageControl. Here's code we need to edit:

.fragment {
    -ms-grid-columns: 1fr;
    -ms-grid-rows: 128px 1fr;
    display: -ms-grid;
    height: 100%;
    width: 100%;
}

Just change class in html- and css-file, for example, to fragment2, and nothing breaks when you navigation back and forward.
