Describe the bug

Description

The Dropdown and Popover components do not trigger when using @vue/compat, even with the compatConfig = { MODE: 3 } setting applied to the component.

Steps to Reproduce

1. Install and configure @vue/compat in the project.
2. Set popover.compatConfig = { MODE: 3 } (or all the used components).
3. Use the Dropdown or Popover components in a template.
4. Observe that the components do not display correctly or fail to trigger their expected behaviors.

Expected Behavior

Both components should work seamlessly under the @vue/compat mode, as MODE: 3 is designed to allow compatibility with Vue 2 components.

Actual Behavior

The components do not render or behave as expected:

• The dropdown does not open when clicked.
• The popover is not displayed when triggered.
