Order of attributes matters to the platform analyzer?

In https://github.com/dotnet/runtime/pull/105409 @akoeplinger needed to reorder platform attributes to fix an issue.  I'm surprised our analyzer depends on the ordering of attributes.  It's not a common characteristic of our API for order of attributes to matter.  Is this intentional @buyaa-n @jeffhandley?
