Combination of roll-up and right-click causes icons to leave the fence

Despite using Fences for years I've only just accidentally discovered the roll-up feature, which is awesome and has helped to tidy my Desktop like never before (out of sight, out of mind ).

Unfortunately there is a problem with right-click options. If I hover over a Fence to open it, then right-click on an icon and choose an option from the right-click menu (say Print or Edit), and if the mouse cursor is above or below the extent of the Fence when the option is clicked, the icon is left on the Desktop outside of the Fence when the Fence automatically rolls back up. 

The symptoms are similar to what's described at https://forums.stardock.com/480810/page/1/#3659613 but the OP in that thread doesn't specifically mention roll-up. FWIW I've not seen this behaviour in fixed Fences, only those that are set to auto roll-up either by double-clicking their title bar or by docking them at the top or bottom of the Desktop.

Obviously I can mitigate this by careful placement of Fences so that things I frequently right-click don't trigger it, but it's annoying. It's also one of those bugs whose triggering is so dependent on personal preference that it's likely many users will never even see it.

I'd be grateful if other users could at least reproduce this so I know it's not a compatibility with something else on my PC. The simplest way to reproduce it is to create a new Fence that's one icon high, drop a .TXT file into it, set it to auto roll-up, place it somewhere near the bottom of the Desktop (so the right-click menu is forced to go above the Fence) then right-click on the .TXT file and choose Edit. You should find the .TXT file sitting on the Desktop outside of the auto-closed Fence.
