STEPS TO REPRODUCE:
- Delete the 'data' folder of an XWiki instance (e.g. XWiki 9.10.1)
- Start the instance with Internet Explorer
- On Distribution Wizard click 'Continue'
- Fill in an Admin account
- Click 'Register and login'
- Click 'Continue'
- On 'Step 2 - Flavor' click on the link of a flavor (e.g. 'XWiki Standard Flavor' or 'Demo Flavor')
The link to the respective flavor's page opens in a new window.
When clicked on the link, new windows to the flavor's page keep opening uncontrollable.
The issue is reproducing only on Internet Explorer (tested on IE 11).
