Omschrijf het probleem / Describe the bug

The asterisk symbol can been seen through a opened select input menu. The asterisk symbols have z-index: 10; which causes this issue.
I've seen this for the select ("keuzelijst") component, but this probably effects more components/situations.

Stappen om te reproduceren / Steps to reproduce

1. Open a form in the admin
2. Add a select ("keuzelijst") component
3. Open the select component configuration
4. Open the "Data source" select input
5. You should now be able to see the asterisks from the "values" tabel
