While copy-pasting similar field in a component of different size, for example dropdowns of different sizes, validations are missing and fields get copy-pasted even if they have different sizes. Validation is still present for copy-pasting different field types altogether like copying a checkbox on dropdown is not allowed. Refer the attached video

Steps to reproduce:
1) Create a new project
2) Create a cube > Add Rigidbody component
3) For rigidbody, In "Collision detection" > Select Continuous Speculative dropdown
4) Right "Collision detection" dropdown > Paste on "Interpolate"

Actual result: Interpolate dropdown shows a blank option

Expected result: Interpolate dropdown either should not allow to paste properties that are not the similar in size or it should display the first or last option appropriately
