The "Add Class" creation Dialog does not focus it's Name Text Field when it's opened when extracting Inline Styles of Properties in the UI Builder Window

Steps to reproduce:

1. Open any Project
2. Create a UIDocument Asset in the Project Browser and open it in UI Builder
3. In the Inspector add a Visual Element and select it
4. Next to a Property click the kebab menu on the left side and select "Set as inline value"
5. Click the kebab menu icon again and select either "Extract Inline Style to Selector" or "Extract All Inline Styles to Selector" and then "New Class"
6. Observe the "Add Class" Dialog that has been opened and the text field in it

Actual results: The only text input field in the newly opened Dialog box is not highlighted or focused, users have to manually select the text field

Expected results: The Text field is automatically focused just like with other creation Dialogs in the Editor (e.g. UI Toolkit's Editor Window creation Dialog)
