Does "Providing Filtering Metadata" function work well in HTML5 client??

Hi,

I use this function on my flex plugin before and run it in flex client, It work well.

But now, I start to develop html5 plugin by using using html client SDK6.5. I encounter some problems.

When I add following paragraph in plugin.xml of HTML5 plugin same with my flex-plugin and run it in HTML client , it not work. 

<metadata> 

<privilege>Company.View</privilege> 

</metadata> 

The plugin's name was always existing on the vsphere client,

even if the user doesn't have Company.View privilege. (It should auto-hide like my flex-plugin running in flex client)

Does it can fix in HTML5 plugin?

Thanks
