If I save a new component in the page editor, you cannot edit it again, but I'm being thrown into some pseudo-preview of the page, with the action bar still suggesting that we're in the editing view, but we are actually not: I have to first switch to the preview, then back to the editing view to be able to select the just added component, then edit it.

Steps to reproduce:
1. Open a page for editing in the page editor.
2. Add a new component to any area.
3. Fill out the forms, then click on "save".
4. You're now entering "pseudo-preview" shown in screen shot 1.
5. Click on "preview page" now to get into the actual page preview. (screen shot 2)
6. Then click on "edit page" to edit the page again.
7. Select the component you've just added. (screen shot 3)
8. You'd be now able to actually edit it again.

Expected behavior:
1. We should remain in the editing view of the page.
2. The newly added component should be selected. It's edit bar should thus be shown in a dark green.

Note, because of MGNLUI-800, don't use "add component" to add a new component, but click into a placeholder.
