Not a rep, visitor like you. I know exactly what you're referring to, and I tried it myself. Scaling doesn't work properly either, which is even worse. The simplest solution is probably to have some kind of checkbox to select whether your edits affect content of your selection or just the container. Another, more refined fix is to have the Node tool select the nodes of all objects that are inside a selection marquee, whether they are parents or children/content. Any edit you make should then affect all objects fully or partially selected. This would give granular control.
I hope that made sense, it got a bit involved :)
Edit: Shift-click lets you set properties of container + content, but not scale properly.
