I am looking for acknowledgement, timeline to fix or any information on the bug that has existed for years regarding the RegularExpression attribute, unobtrusive client side validation and the option for case insensitive matching. I've searched the discussions and issues here on codeplex to no avail.

I am getting the following error when including (?i) in my regular expression:

0x800a139a - JavaScript runtime error: Unexpected quantifier

SyntaxError: Unexpected quantifier
at Anonymous function jquery.validate.unobtrusive.js:348:9

Furthermore a blog was written in 2013 covering in detail the issue. http://blogs.msdn.com/b/tilovell/archive/2013/05/08/regular-expressions-are-different-in-javascript-and-unintrusive-validation.aspx

Please shed some light on what's the holdup?
