range.js initialization in IE 8/9

[dosena]

Line 77 in the $.Range constructor is problematic if you've included jquerypp in and there's no DOM yet.

B/c this.win.document.body is null, this.range doesn't get assigned.

If this.range doesn't get assigned, the module setup (anonymous) function chokes at line 642 ( ... fn.compare = range.compareBoundaryPoints ? ...) and bails w/ an exception.

This is especially dangerous if you, like me, happen to have range.js concatenated w/ a bunch of other files (and minified) - those other files' initialization may not run b/c of the exception.
