web pdf viewer cause viewer crashe

[Didier Corbasson]

Seams to appear every time you open a report from another menu context ( ex delivery slip report in the sale menu )

message in the console
"PDF 1cb42fe84eb448c61f7ebe2913f2a1 [1.4 ReportLab http://www.reportlab.com / -] (PDF.js: 0.8.990)" viewer.js:3178
"offsetParent is not set -- cannot scroll" viewer.js:158
NS_ERROR_FAILURE: pdf.js:5789

You can easily reproduce the error this way:

->Place an order (sale order) and continue the process until delivery
->click the button to see the "delivery slip"
  the breadcrumb shows "Saleorder -> SO ... -> OUT ...
  we are now in the correct form of delivery (but we are still in the sales menu)
->click on the Print button and select the printing model

-> Crash

->press F5

  We are now in the Warehouse menu, subcategory delivery.
  the breadcrumb shows "Delivery slip-> OUT ...
->click on the Print button and select the model printing

-> Good
