Editor ES2 Feature Level preview and Mobile Preview PIE do not limit materials to 8 textures

Open a new project and create a new default map

Create a new material and add 9 TextureSamplers each with a different texture, and 9 Add nodes, and connect them all to add the output of all the textures together.

Place the material on the floor.

Use editor Feature Level ES2 and verify the material looks fine

Use mobile PIE and verify the material looks fine.

Launch on an Android device (default project setting should be ES2 only) and verify the material is replaced with the checkerboard pattern.
