- Use closeTimeout ref to track the active closing transition timeout. - Clear closeTimeout and clean up previous form state on openDialog. - Replace promise-based delay in handleClose and onSubmit with a cancelable window.setTimeout.

Fixes the issue where opening another inputDialog immediately after closing one results in a blank UI.
The Problem
When a dialog is closed (submitted or canceled), NUI sets a 200ms timeout to clean up the form state after the fade animation finishes. However, the client-side promise resolves immediately, meaning a script can trigger a new dialog before that 200ms is up. When this happens, the new fields are loaded, but the pending timeout from the first dialog still fires and clears them out.
The Fix
closeTimeoutref to keep track of the close animation timeout.handleCloseandonSubmitto use standardsetTimeoutwith the new ref instead of the promise-based wrapper.
