difference between CTRL-A and manual selection of all items

Description

The "CTRL-A"-hotkey differs a little bit from the behaviour of manual selection of all items on a board. If one selects all items with CTRL-A the following is missing:

• statusbar doesn't show the selection-count
• properties pane doesn't shows the common item-parameters
• properties pane still shows a string "nothing selected"

Steps to reproduce

1. open attached project, open board: CTRL_A.zip
2. appearance-panel-->selection-filter-->enable all items
3. appearance-panel-->choose preset "All Layers"
4. box-select all items on the canvas and observe (see left picture):

• 22 items reported as selection on statusbar
• also properties pane (left side) is active

5. LMB on empty canvas to clear selection
6. hotkey "CTRL-A" to select all, notice (see right picture):

• no selection-count on statusbar
• properties pane (left side) is empty
