Description Said Abou-Hallawa 2018-07-24 16:49:26 PDT 
A problem could happen if we are replaying multiple display lists to the same drawing context. When replaying its DisplayListItems, the DisplayList expects to find the state of the drawing context to be exactly the same it was at the time it was recorded.
