When Setting the scale. Its size is reduced.

Expected result is framesize shouldn't change, but visual size should be 5x larger

UPDATE: Did some more testing. If you setscale to MyBaseFrame it works fine. So there's a bug or something with setpoints and scale
Tested this on the PTR today, and still bugs out

local FrameBorder = {
   bgFile   = '',
   edgeFile = [[Interface\DialogFrame\UI-DialogBox-Border]],
   tile = true,
   tileSize = 16,
   edgeSize = 6,
   insets = {
      left = -4 ,
      right = -4,
      top = -4,
      bottom = -4
   }
}

if MyBaseFrame == nil then
   MyBaseFrame = CreateFrame('Frame', nil, UIParent)
   MyBaseFrame:SetSize(100, 100)
   MyBaseFrame:SetPoint('LEFT', 100, 0)
end

if MyScaleFrame == nil then
   MyScaleFrame = CreateFrame('Frame', nil, MyBaseFrame)
   MyScaleFrame:SetAllPoints()
end

if MyFrame == nil then
   MyFrame = CreateFrame('Frame', nil, MyScaleFrame)
   MyFrame:SetAllPoints()
   MyFrame:SetBackdrop(FrameBorder)
end

local MB = MyBaseFrame
local SF = MyScaleFrame
local MF = MyFrame


SF:SetScale(5)

C_Timer.After(1, function() print(MF:GetSize()) end)
