828599 - Cannot set custom properties on Typed Arrays

Status: RESOLVED DUPLICATE of bug 695438

(Core :: JavaScript Engine, defect)

Steps to reproduce:

I am using typed arrays to map to WebGL vertex structures, and it is extremely convenient to store stride / offset values on the typed arrays. This works fine in Webkit.
var x = new Float32Array(1)
x.stride = 1
and then:
x.stride == undefined


Actual results:

Custom properties on typed arrays dont work


Expected results:

They should work because its makes it easy to keep important values such as vertex stride on the typed arrays. This way you can just pass around a typed array and util vertex generation code can use them without extra objects to keep these values.
