Enabling CListCtrl marquee selection - windows

Question

I'm using an MFC CListCtrl in report mode and enabled full-row selection and alpha-blended marquee selection via
const DWORD extendedStyle = m_wndList.GetExtendedStyle();
m_wndList.SetExtendedStyle(extendedStyle | LVS_EX_DOUBLEBUFFER | LVS_EX_FULLROWSELECT);
Marquee selection, i.e., spanning a selection rectangle across multiple items while holding the left mouse button, works if I start the selection in the area of the CListCtrl window which is not occupied by items.
However, if I click on an item and want to start marquee selection from there, the selection rectangle is not created. This is in contrast to, e.g., Windows Explorer where marquee selection also works if initiated from a selected item.
As MCVE, I've used the 'New Project Wizard' on Visual Studio 2017 and created a dialog-based MFC Application and placed a 'List Control' on the dialog resource. This list control is wired to a member variable CListCtrl m_wndList via DDX and gets the extended styles as mentioned above.

Can anyone point me in the right direction and explain, how to enable marquee selection that is starting from an individual item in the list control?
Edit: Here's an example of marquee selection from Windows Explorer in Windows 10
