Looking for addon causing a bug

Any addon showing a context-menu can causes it. But there is nothing wrong with the calling:
ClearMenu() AddMenuItem ... ShowMenu(), right?

How to reproduce:
Do in chat window:
1. /reloadui
2. /script ClearMenu() AddMenuItem("") ShowMenu() ClearMenu()
3. Go and use an item of your inventory using context-menu

unsecure code?!?

Try this:
1. /reloadui
2. go and open journal and right-click a quest to open a context-menu. In fact any build-in context-menu would be ok. You could also open the context-menu of the inventory.
3. /script ClearMenu() AddMenuItem("") ShowMenu() ClearMenu()
4. Go and use an item of your inventory using context-menu

now the same code is secure.

The critical call is AddMenuItem("")
Here is another example:
"secure" code adding a normal button below the context-menu

local good = WINDOW_MANAGER:CreateControlFromVirtual("GoodBoy", ZO_Menu, "ZO_DefaultButton")
good:SetDimensions(320, 32)
good:SetAnchor(TOPLEFT, nil, BOTTOMLEFT)
good:SetText("Click me")

"unsecure" code adding a ZO_MenuItem control.

local bad = WINDOW_MANAGER:CreateControlFromVirtual("BadBoy", ZO_Menu, "ZO_MenuItem")
bad:GetNamedChild("Name"):SetText("Click me")
bad:SetAnchor(TOPLEFT, nil, BOTTOMLEFT)
bad:SetHidden(false)

It depends on who uses the template ZO_MenuItem first?!?

Seems to be a game-in bug. Or AddMenuItem should not be public. What else should be used?
