Stop TextBox's view area from snapping back to beginning when unfocused

When the amount of text exceeds the TextBox’s width, the TextBox’s view area snaps back to the beginning when you scroll to the end then unfocus the TextBox. I want it so if you leave the TextBox’s CursorPosition at any position and unfocus the TextBox the TextBox’s view area stays at that position.

I tried doing what I wanted by placing a TextBox inside a ScrollFrame and having the TextBox’s AutomaticSize = X and the ScrollFrame’s AutomaticCanvasSize = X. I then use the following code to “push” the ScrollFrame’s X-Offset CanvasPosition so it mimics what the normal TextBox does.

local OldAbsoluteCanvasSize = 0
ScrollFrame:GetPropertyChangedSignal("AbsoluteCanvasSize"):Connect(function()
	local NewAbsoluteCanvasSize = ScrollFrame.AbsoluteCanvasSize.X
	if NewAbsoluteCanvasSize - ScrollFrame.AbsoluteSize.X <= 0 then
		return
	end
	ScrollFrame.CanvasPosition = Vector2.new(ScrollFrame.CanvasPosition.X+(NewAbsoluteCanvasSize-OldAbsoluteCanvasSize))
	OldAbsoluteCanvasSize = NewAbsoluteCanvasSize
end)

However, it only mimics the normal TextBox if I type new letters at the end and fails everywhere else. Does anyone know how to disable or work-around this behaviour?
