Agent profile description does not disappear after quick mouse hover (UI freeze)

[bazsii2000]

When selecting an agent from the profile dropdown (via @cl.set_chat_profiles), the markdown_description panel gets stuck if the mouse cursor is moved quickly over the dropdown items. The description from one of the previously hovered profiles remains visible, even after the selection dropdown is closed.

The issue occurs both:

-In the default Chainlit UI
-And when the Chainlit chatbot is integrated into an external frontend (react)
The issue reproduces in Chainlit 2.2.0 and still exists in the latest Chainlit 2.4.1.

To Reproduce
Launch a Chainlit app with multiple profiles via @cl.set_chat_profiles().
Hover over the dropdown profile list (e.g., Agent1, Agent2, Agent3, etc.).
Quickly move the cursor between multiple profiles (e.g., fast scroll or swipe).
Observe how one of the markdown_description popups (e.g., "Test2" or "Test4") freezes and stays visible.
Expected behavior
The description panel (markdown_description) should disappear as soon as the profile dropdown closes or when no profile is hovered.

Example: Description "Test2" and "Test4" stuck on screen after moving cursor quickly.
