Resizing application window causes main menu to enter screen

In the Qt Quick Demo - StocQt example, when you are in the page that is displaying a chart, strange behavior occurs when resizing the application window horizontally. The main menu page containing the list of the different stocks will partially enter the screen when resizing horizontally. When you stop resizing the application window, the screen goes back to normal with the page that is displaying a chart.

This does not occur in the chart page when resizing the application window horizontally, nor does it occur in the chart page when entering it with left-click dragging the screen to the left while in the list page. It does not occur at all while resizing the application window in the list page. It only occurs if you left-click a stock in the list page, and then try to resize the application window horizontally while in the chart page.

Steps to reproduce:

1. Left-click "AMD" to view the stock chart. Notice that you are now in another page.
2. Resize the application window horizontally. Notice that it tries to drag the list page back into the screen, and that this behavior stops once you stop resizing.
3. Left-click drag the screen to the right. Notice that you are back in the list page.
4. Left-click drag the screen to the left. Notice that you are back in the chart page.
5. Resize the application window horizontally. Notice that nothing strange happens.
6. Repeat step 5, but in the list page. Notice that nothing happens as expected. This behavior does not occur at all in the list page.

Expected behavior:

The page containing the list should not enter the screen when resizing the application window. It should still fully show the page containing the chart.
