title: Shiny large plots overlap
body: <p>I'm producing some pretty big plots (a grid of about 100 bar graphs). I use verticallayout with the default of <code>fluid = TRUE</code>. I have the size set in my server function<br>
  <code>output$hist7 &lt;- renderPlot({ #actual plot excluded though any will do
  }, height=1000, width=800)</code></p>
  
  <p>When I try to place text below this plot with <code>h1("text here")</code>, 
  "text here" ends up in the middle of hist7. This issue does not occur with any of the plots I didn't set the size for, this is the only one large enough that I have to set a size to prevent shiny scaling it down</p>
