Am I correct in thinking that visual effects are still not working in HTML5 even though the dictionary says they are supported? I get the following error thrown and the stack halts:

missing function: _ZN7MCStack38view_platform_updatewindowwithcallbackEP10__MCRegionPFbP14MCStackSurfaceS1_PvES4_

Luckily I think I can fake what I need using transparency tricks, but it will be a hassle compared to a visual effect.

Visual effects are even hard to get by pure JavaScript. Some authors use SVG or CSS for similar effects.

So yes, it is not available -- and it will probably never be implemented in the HTML5 standalone builder.
