"Add Angle Random from Curve (Constant per-particle)" Checkbox goes outside of the Block area when "Sample Mode" set to "Random Constant Per Particle" and changes Channels value (X, Y, XY, XYZ) under "Add Angle Over Life (Attribute Curve)" Block, However Block collapse and expand dropdown icon also goes outside of the Block area

Steps to repro:
1. Create a new project
2. Windows > Package Manager > Visual Effects Graph > Install
3. Project > Packages > Visual Effect Graph > Editor > Templates > Open Default Subgraph Block
4. Focus on "Block Subgraph"
5. Press space twice to add blocks > "Add Angle over Life (Attribute)" block
6. Sample Mode > Random Constant Per Particle
7. Change Channels value (XY, YZ, XZ, XYZ)

Actual Result:
"Add Angle.XYZ Random from Curve (Constant per-particle)" checkbox goes out of the Block area on changing Channels value

Expected Result:
"Add Angle.XYZ Random from Curve (Constant per-particle)" checkbox should be inside the Block area and interactable
