bug 521 - IE8 won't render in Standards Mode.... if rendered in a Web Slice

Issue: #521
Affects: IE8
Status: Microsoft has confirmed this will NOT be fixed in IE8 RTM

With much rejoice Web Developers everywhere cheered when Microsoft announced that IE8 would render in its best effort at Standards Mode by default when IE8 ships. This is still true, with a few exceptions.

1.) Intranet (e.g. internal network sites) will still render in IE7 mode by default [ITNOBC*]
2.) When you add one of the nifty IE8 Web Slices (e.g. brand spanking new to IE8, never ever supported in IE6 or IE7 before)... even when you serve up 100% valid Standards Based HTML content... IE8 will ALWAYS, Without exception... render it like IE7.

So its another case of 2 steps forward, 1 step back. You can update/maintain your pages to ensure IE8 renders them well just like they appear in Firefox, Safari, Chrome and Opera, etc. but if you want to add one of these Web Slice (think mini-graphical RSS) things to your page, you'd better make sure that that content renders just as well in IE7 mode.

Don't bother with Conditional Comments looking for IE7 though, because the Web Slice "engine" will report itself as IE8.

Developers find it very puzzling that new features are broken right out-of-the-gate when so much focus for IE8 was on fixing the mistakes of the past. Oh well.
