Steps to reproduce the problem:
Note: this error is discovered in a C# automated test suite
1. Launch Google Chrome in headless mode;
2. Navigate to 'chrome://clearBrowserData'
3. Try to find elements (checkboxes for data type selections, dropdown for the search back period and "Clear browsing data" button) with Selenium.

What is the expected behavior?
Even if I'm in the "headless" mode, I should be able to clear my browsing data like I would do without the "headless" argument.

What went wrong?
The page is not correctly loaded and I'm unable to select the appropriate elements with Selenium. 

Did this work before? N/A
