Base Pass Instruction Count increases on Compile and Save, then resets upon reopening Material

Material Base Pass Instruction Count will change from a value established when plugging in components pre-compile to a higher value on post compile, but when the material is reopened the count reverts back to pre-compiled level instruction count. The Shader Complexity View mode also seems to be using higher values.

Also reproduced in Launcher 4.9 Preview 4 and Main-CL-2666305

1. Open QAGame Editor
2. Create a New Material
3. Set the Blend Mode to Translucent
4. Set the Shading Model to Unlit
5. Under Window Menu, Check Stat to see the Material Stats
6. Add a Texture Sample of Texture2D'/Engine/EngineResources/AICON-Green.AICON-Green'
7. Plug the RGBA output pin of the Texture Sample into the Emissive Color Input
8. Plug the Alpha output pin of the Texture Sample into the Opacity Input
9. Note Base Pass Shader without Light Map: 6 instructions
10. Compile Material
11. Note Base Pass Shader without Light Map: 25 instructions
12. Save and Close Material
13. Reopen Material

RESULTS: The Base Pass Shader without Light Map instructions have returned to 6 instructions, doing anything to initiate another compile will reset the instruction count to 25.

EXPECTED: The Instruction Count should not change unless additional information is added within the Material or an Attribute of the Material is changed.
