When we destroy the fixed layer because we think it's outside the viewport, the render tree is actually needing layout:
RenderView 0x1180834f8 at (0,0) size 1143x605 (needs layout: positioned child)
and the fixed layer has a bogus 0,0 location:
layer 0x10d67eca8 at (0,0) size 196x606 scrollWidth 204 (composited, bounds=at (0,0) size 196x605, drawsContent=1, paints into ancestor=0)
RenderBlock (positioned) 0x10d69ded8 zI: 99 {DIV} at (0,0) size 196x608 [bgcolor=#FFFFFF] id="nav-menu-wrapper" class="nav nav-one-col-hp jfk-scrollbar-borderless left-nav-pinned" (needs layout: self)
RenderBlock 0x10d652d28 {DIV} at (28,3) size 152x553 class="browse-sidebar"
