Getting Vector Parameter Values from a Dynamic Material Instance with 1 or more vector parameters returns an empty array

This is not a regression. Tested in //UE5/Release-5.0 CL20979098

The array for Vector Parameters isn't getting populated when called from a Dynamic Material Instance.

1. Create or open any project
2. Create a new material named M_Test
   1. Add 1 or more Vector Parameter nodes then connect it to Base Color
   2. Compile, save, and close the material
3. Create a new Blueprint Actor named BP_DMI
   1. Add a Cube Component
   2. In the Event Graph off of Event Begin Play create a 'Create Dynamic Material Instances(Cube)'
   3. Set the Source Material to M_Test
   4. Off the Return Value create a 'Get Vector Parameter Values'
   5. Off the Array of that node create a 'Length' node
   6. Connect the Length node's output to a 'Print String' node
   7. Connect up the execution pins
   8. Compile, save, and close the Blueprint
4. Place BP_DMI in the scene
5. Play in Editor
6. Observe the value printed to the string

Expected Results:
The length of the array is equal to the number of Vector Parameters in the Material.

Actual Results:
The length returns 0. The array isn't populated.
