The second tooltip in the Sentiment view should say "did not pick any sentiment" but displays the same message as the first tooltip ("had a sentiment").
For example, looking at https://2023.stateofhtml.com/en-US/features/#all_features, with "Group by" set to "Sentiment", the second tooltip that gets displayed when one hovers the 54.5% for "Landmark elements" says "54.5% of respondents had a sentiment". That should be "54.5% of respondents did not pick any sentiment".
(The tooltip displayed when one hovers the more detailed bar right above that figure correctly says "and did not pick any sentiment")
Actually, that extends to the third tooltip as well when it exists, which also says "had a sentiment" instead of "had a negative experience sentiment".
