I've confirmed that overall rendering performance is not degraded by this
patch, using iBench 5.0.

Here is the result:

(1) without the patch

 HTML Load Speed                     
   All iterations      16.49            
   First iteration (downloaded)      4.6            
   Subsequent iteration (cached)      1.7            
 XML / CSS Load Speed                     
   All iterations      12.24            
   First iteration (downloaded)      2.55            
   Subsequent iteration (cached)      1.94            
 JavaScript         0.17
 HTML W3C DOM
   Overall      0.34            
   Sorting      0.25            
   DOM      0.9    

(2) with the patch

 HTML Load Speed                     
   All iterations      15.51            
   First iteration (downloaded)      3.89            
   Subsequent iteration (cached)      1.66    
 XML / CSS Load Speed                     
   All iterations      12.19

   Subsequent iteration (cached)      1.92

   Overall      0.35
