+This tests that a top layer element's containing block is the initial containing |
+block. The dialog is positioned at (1200, 1200) and the window is scrolled to |
+(1000, 1000) so the dialog should be positioned at (200, 200) relative to the |
+viewport. |

+ This dialog should be onscreen with a width of 50% of the viewport. It is the child of an narrow element |
+ positioned off screen, but its containing block is the initial containing block, so its |
+ position and percent lengths are relative to that. |
