Description
The designer doesn't properly parse and represent tagprefixes for user controls.

I have this

<%@ Register TagPrefix="lmx" TagName="ucBottomCenter" Src="ucBottomCenter.ascx" %>
<%@ Register TagPrefix="lmx" TagName="ucTopCenter" Src="ucTopCenter.ascx" %>

in an aspx page.  I declare the controls as

<lmx:uctopcenter id=MainImageUserControl  runat="server">
</lmx:uctopcenter>

and later

<lmx:ucbottomcenter id=BottomCenterUserControl
                                runat="server">
            </lmx:ucbottomcenter>

in that aspx page.  I get

"Error: Parser Error: Unknown server tag 'lmx:ucbottomcenter'"

in the designer. If I swith the Register tags around, the first one
won't parse.

I definitely should be able to have two controls declared with the
same prefix.
Steps to Reproduce:
1.  Create new ASP.NET application
2.  Add two user controls to the project.
3.  go to the main page, and use Insert|User Control to add the two user controls to the main page.
4.  Go to the ASPX page and make the tagprefixes in the <$@ register %> tags the +same+  (Note, this should be allowed.
5. Go to the designer, and note that it shows a parser error.
