#1455 Javascript Regular Expression index wrong

[Ichai]

The Regular expression in internet explorer get a result with index and lastIndex attributes.
In HTMLUnit the index is 0 instead of 30 and the lastIndex does not exists.

Step to reproduce :
open the html file in explorer and see the values in the alert. Compare them to the values in HTMLUnit.
