Dify version

1.9.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

1. When creating a Dify project, set a custom field with the type of "select".
2. Publish the Dify App.
3. Ask something casually to make the dialog box exceed the screen length.
4. Click on the dialog settings in the upper right corner.
5. Select the preset custom fields, and you will see that the options are obscured.

✔️ Expected Behavior

It is expected that the selectable options should be displayed above the Settings Dialog and not be obscured.

❌ Actual Behavior

As shown in the figure, the select options are blocked by the Dialog.
