[ccla][patch] GFX performance degradation on WebKit

Reported by: Scott Andrews Owned by: Eugene Lazutkin
Priority: high Milestone: 1.5
Component: DojoX GFX Version: 1.4.2
Keywords: webkit, gfx, border-style, border-color Cc:
Blocked By: Blocking:

Description

dojox.gfx._base._getTextBox uses a DOM node positioned off screen to calculate font sizes. Over time with WebKit? browsers, the style attribute of the node becomes excessively large with repeated redefinition of "border-style: initial; border-color: initial;" with a duplicate entry for every invocation of the function.

Verified with Dojo 1.4.2.

A simple work around is to set the borderWidth property instead of border. For example: if(dojo.isWebKit){

s.borderWidth = "0";

}else{

s.border = "0";

}
