JS: small issue with Std.is and Firefox

[mockey]

Std.is(elem, Element) returns false for an Element in Firefox, because
typeof Element
returns "object" in Firefox while it returns "function" in WebKit browsers. Modifying the check in js.Boot.__instanceof to:

if( (untyped __js__("typeof"))(cl) == "function" || (untyped __js__("typeof"))(cl) == "object" ) {
  ...

seems to fix this.

typeof HTMLElement returns function in Firefox over here?

Std.is(elem, Element) also seems to work as expected.

Seems similar to #2441

In my case it was a pretty old version of Firefox (11.0) which returned object.

Closing this since it seems to affect an old version of one browser. If there are any recent browsers that do this, please reopen.

Safari does this. Here is a proposed fix: #2857

It's also the correct behaviour defined in the spec.

Too late for 3.2, possible for 3.3.

A fix from me is already merged since last year: #2857. This can be closed.
