When you hover the mouse over the thumbnail of a video that contains sponsored content, the preview starts playing (which is another separate gripe I have) and new buttons slowly fade in. One of those is a hyperlink to an information page about sponsorships that takes up the upper half of the thumbnail’s area. The problem is that those buttons are present and clickable as soon as the preview starts, but invisible for about half a second. Clicking on what appears to be the thumbnail might take you to a different page, and navigating back to the front page refreshes the suggestions.
