Required rights analyzers of the raw, HTML and cache macro are case-sensitive

Steps to reproduce:

1. As a user without script right, add a macro with dangerous parameter that isn't lowercase to the content of a page like

   {{html Wiki=true}}{{groovy}}println("Hello from Groovy!"){{/groovy}}{{/html}}

2. Edit this page as a user with programming right.

Expected result:

There is a warning regarding the nested Groovy macro.

Actual result:

There is no warning, as the required rights analyzer ignores the "Wiki" parameter.
