• I have checked for existing issues to avoid duplicates

Actual Behavior

The selected date gets cleared (and is replaced by the placeholder) when the user clicks out of the component for the "bs", "it-CH" locales.

Expected Behavior

• The selected date would remain, like it does for the "en" locale
• Add test coverage for future support

Thanks, @annierm18, for logging the issue. We have used the temporary fix based on Blake's comment - #4583 (comment). But need to fix this issue in the component.
