Many uses of secure snippets failing on TBC beta

[Gello]

On the BC beta:

local button = CreateFrame("Button", "SecureTest", UIParent, "SecureActionButtonTemplate")
button:SetSize(36,36)
button:SetPoint("CENTER")
button:SetNormalTexture("Interface\\Icons\\INV_Misc_QuestionMark")
 
button:SetAttribute("type","spell")
button:SetAttribute("spell","Life Tap")

Functions as expected.

Once you start getting snippets involved, such as:

local button = CreateFrame("Button", "SecureTest", UIParent, "SecureActionButtonTemplate")
button:SetSize(36,36)
button:SetPoint("CENTER")
button:SetNormalTexture("Interface\\Icons\\INV_Misc_QuestionMark")
 
button:SetAttribute("type","spell")
button:SetAttribute("spell","Life Tap")
 
SecureHandlerWrapScript(button, "OnClick", button, [[
  print("click")
]])

It starts throwing errors like this:

Message: Interface\FrameXML\RestrictedExecution.lua:473: Cannot call restricted closure from insecure code Time: Sun Apr 4 16:24:56 2021 Count: 2 Stack: Interface\FrameXML\RestrictedExecution.lua:473: Cannot call restricted closure from insecure code [string "=[C]"]: ? [string "@Interface\FrameXML\RestrictedExecution.lua"]:473: in function <Interface\FrameXML\RestrictedExecution.lua:447> [string "=(tail call)"]: ? [string "@Interface\FrameXML\SecureHandlers.lua"]:285: in function <Interface\FrameXML\SecureHandlers.lua:279> [string "=(tail call)"]: ? Locals: (*temporary) = "Cannot call restricted closure from insecure code"

My state drivers are failing with a similar issue. It seems like this is may be due to taint with beta debug code.

Today's patch seems to have fixed my issues with the secure environment.
