Root of a request bounds action

[georghinkel]

I have some trouble to understand the requestBounds-action. As far as I understand, the purpose of this command is to request client-side layout information because the server typically lacks information about bounds especially for text boxes. However, the protocol implementation suggests that one has to send the entire graph, not just the part of it for which a layout is needed. Is there a way to only send a fraction of the graph? Typically, I only want to have the layout information for a few elements.

Further, when sending a graph without layout information (since this is what I expect from the client), the client crashes with a type error, saying that bounds were missing (using @eclipse-glsp/client 2.1.1). How can I avoid these?
