[Demo]: closing data validation window freezes

Steps to Reproduce

Demo: Work with a Database

Browser: happens on both windows and mobile

1. Add New Expense
2. Enter alphabets (non-number) on to "Unit cost" cell
3. Click "X" instead of cancel or retry when the dialogue pops-up => Demo freezes and can't continue until refresh

Current Result

The demo freezes and refresh of browser is required

> In Mobile, input will be removed from "Unit cost" when the category is changed

> On Windows browser, it remains the same even after the category is changed

Expected Result

 should not allow user to click X and close the window? should only allow them to Cancel or Retry? (not sure if this should be handled by the App or the component)
