Upgraded Storybook from 5.2.4 to 5.2.6. This warning message appears in browser's console when I open the page in mobile view. It doesn't appear on desktop or in version 5.2.4.

To Reproduce
Steps to reproduce the behavior:

1. Visit Storybook locally
2. Change device type in Chrome Dev tools to mobile
3. Reload the page
4. See error

Expected behavior
No warnings should appear in console. Like it was in 5.2.4.
