Window can't be reduced horizontally when items viewed as icons

[Nairwolf]

I can't reduce the window horizontally *when* the menubar on the left is reduced to zero.

Steps to reproduce this bug :
*Launch xfce4-appfinder in minimized size
*Go to preferences and click on "view items as icons"
*Reduce the menubar on the left to zero (it should not be displayed)
* Try to reduce horizontally the right side of the window (from right to left)
* Nothing moves, it's blocked

Behavior expected :
The window should be reduced. If you try to reduce the vertical size of the window, it works.

Note :
It's really important to reduce the menubar on the left because if it's not completely reduced, it's possible to reduce the window.

Package used :
On Xubuntu 16.04 amd64, with the version 4.12.0-2ubuntu1 of xfce4-appfinder.

unable to confirm - remaining window reduces as much as any other window here

Confirm when items are viewed as icons - in fact extending the window so icon rows populate in longer rows stops the window from reducing afterwards

[Kev Bowring (flocculant)]

Open appfinder.

From preferences set Appearance to View as icons.

Minimise left hand 'menu' sidebar completely.

Extend window to right - expanding the icon view - try to reduce window size. Fails here.

Normal behaviour seen when the menu sidebar is slightly visible

Status changed to 'Confirmed' because the bug affects multiple users.

I can reproduce with the current release but not the current master, ported to gtk3.
Please take a look.

Fixed by the gtk3 port.

The switch to a GTK3 build was done in 18.10.

Correction: in 18.04
