Description
T24011 - SurveyJS Creator v2 > Styles doesn't work for custom property
https://surveyjs.answerdesk.io/internal/ticket/details/T24011
To reproduce the issue, run this demo: View CodeSandbox.
Issue: Select the first question and navigate to the General property grid tab. Notice that the "Accepted identity verifications" property grid editor uses different styling.
Expected behavior: select the question's default value property grid settings and activate the dialog. The property grid editor should appear as within this dialog.
