What's written in the document doesn't match how DS actually works

I'm not sure if I'm doing something wrong or missing something, but in the document it says

"Alternatively, start typing a string and press Ctrl+Space to display a list of properties, IDs, and code snippets"

https://doc.qt.io/qtdesignstudio/qtquick-positioning.html#setting-bindings

However, when I opened connection editor and typed something, DS automatically showed me the list of suggestions, without me pressing Ctrl+Space. Also, even when I pressed Ctrl+Space in the middle of typing, it didn't show anything.
I'm assuming DS used to show a list of suggestions with Ctrl+Space and now it's updated to be shown automatically without it, then the document was missed to get updated.
