Location Bar does not show new location if I click on File System

If Thunar is opened in my home folder with the Location bar set to Toolbar Style and I then click on File System on the left hand side, the Location Bar does not change to reflect the new location. It shows all the correct system folders in the right-hand pane but the location bar still shows my home folder. There is a change in that the folder button is no longer highlighted, so presumably the highlight has moved to the root folder ('File System') but you have to click the small left-pointing arrow beside the location bar to bring it into view.

Admittedly, this is only a minor glitch and I did wonder if it was a deliberate feature to keep things simple by still showing the user's home folder. However, other file managers I checked (Caja, Nemo and PCManFM) work as expected so I am thinking it may be a bug.

Another way of looking at the same bug is that maybe when I open Thunar it should show all three buttons in the location bar to begin with, not just the one with my name on.

Tested on Thunar 4.16.8 and 4.16.10.
