Issue:
In recent Opera versions onload doesn't work when a MS .eot webfont is used.

This affects both the HTML/tradition onload="..." as well as the W3C DOM object.addEventListener().

Opera 10.63 (Win7): Tested, works
Opera 11.00: Not tested, unknown
Opera 11.10 (Win7): Tested, BROKEN
Opera 11.11 (Win7): Testen, BROKEN
Update 20110629 Opera 11.50 fixes the issue

Test pages, these pages are the same except that on the first page the webfont doesn't actually get used -- only a nonexistent #f get assigned the webfont.

No webfont, works (source)

MS webfont, doesn't work! (source)
