Bug Description

The ui5-dialog currently contains logic in the onEnterDOM hook that depends on the component’s state. This is problematic, as described in the official UI5 Web Components documentation:
https://sap.github.io/ui5-webcomponents/docs/development/deep-dive-and-best-practices/#onenterdom-and-onexitdom

"These hooks are completely independent of the component's rendering lifecycle, and are solely related to its insertion and removal from the DOM."

This means they are also independent of the component’s internal state. Using them in conjunction with state-dependent logic can result in incorrect behavior or broken functionality.
