Page picker space completion does not complete properly in two cases

[jmatraszek]

Hey, I open Page Picker with Ctrl-k and hit space to complete the name of the current page (my main use case is that I want to easily be able to create pages nested under the current page).

When the current page name contains no spaces, everything works as expected.

When the page name contains a space, only the first word is completed. In this case, I was expecting to get test page/ when I hit space.

When I have pages nested even deeper, it only completes to the first page name. Here I would expect to get everything completed, all levels. Hitting space for each level of page name completion would also be ok.

Thanks
