Required asterisk rendering multiple times

[lucasbode]

Describe the bug
After updating to @formio/bootstrap@3.1.4, all of our required asterisks following our labels are rendering multiple times. If I revert back to 3.1.3, the extra asterisk no longer appears.

To Reproduce
Steps to reproduce the behavior:

1. Render a form using the following dependencies..

"@formio/angular": "^9.0.1",
"@formio/js": "5.2.6"

2. Add a required input to the form

Reference the following stackblitz to observe the behavior - https://stackblitz.com/edit/stackblitz-starters-syxd45co?file=package.json

Expected behavior
A single red asterisk should appear.
