DropDown Interaction issue

Hi,
    We are facing an issue where the UI TextMesh Pro dropdown interaction is not working, but other UI elements are functioning correctly.

Consider the following scenarios:

Scenario 1:

We have a screen space overlay canvas that is converted into a world space canvas at runtime.

Methods used for UI interaction:

1. Ray interaction.
2. Collider surface for interaction.

In this scenario, the UI dropdown is not working.

Scenario 2:

We have a direct world space canvas, and using the same methods, the interaction works fine.

Please help us to resolve this issue.

FYI - we are using the meta sdk version 65.0.0

Thanks in advance.
