IE 9 in IE8 Browser Mode/Document mode supports SVG?

I just upgraded to IE9 to do cross browser compatibility testing of my site, which uses Raphael.js. I know my site and its Raphael.js graphics work in IE8 proper using VML, but for some reason, when I set IE9 to have IE8 Browser Mode/Document Mode, Raphael.js tries to use SVG instead of VML. This doesn't happen when I set IE9 to IE7 Browser Mode/Document Mode; that is, Rapahel.js uses VML. Why does IE9 think that IE8 supported SVG?

The problem seems to be that win.SVGAngle is defined in IE9's IE8 mode, but isn't in normal IE8. - Aaron Gibralter
This doesn't appear to reproduce in the latest internal build. Is there a URL I could try? - EricLaw
I don't have a URL with that anymore, but the line of code from Raphael.js is here: github.com/DmitryBaranovskiy/raphael/blob/master/raphael.js#L92 - window.SVGAngle was defined for me in IE9's IE8 mode... I'm not on my PC right now so I can't tell you which version I have... but I can check on Monday. - Aaron Gibralter
IE9 RC improved other discrepancies between IE8 and IE9-in-IE8-mode. Does this issue persist as of February’s IE9 Release Candidate? - Alan H.

I know nothing about Raphaël, but I do know that IE9 reports its JScript Version incorrectly. No matter what version you have Browser Mode/Document Mode set to, @_jscript_version returns 9. If Raphaël decides whether to use VML or SVG based on @_jscript_version, it could cause trouble.
