Steps to reproduce
- Use the Chrome or Chromium.
- Clear impCount cookies for wikipedia.de to make sure the banner impression limit won't prevent banner displays.
- Clear cat cookie for wikipedia.de to reset banner display preventing cookie that is set after closing or donating.
- Open www.wikipedia.de
- Close the banner.
- Reload the page.
- The banner is not displayed.
- The banner is displayed, ignoring that the previous banner was closed.
- This is probably happening in wmde/banner-server
- The banner impression limit (which seem to be based on similar logic) is working.
