If you want to fight with it then my first idea would be to find how method AST is built in sugs menu. Then try to look at senders of #astForStylingInCalypso which was implemented to support styling of remote methods. Try to use it somehow for sugs menu too.

Maybe it will fix everything

Yes, i will have a look - i need the right click menu to properly work so i need that to be fixed. The workaround i used was to just disable suggestions by returning empty suggs collections, but i will see if i can do something better.

Thanks Denis.
