| Records events related to click through rate (CTR) calculation. |

| The CTR can be calculated by computing "Interacted" / |

| were clicked. For sliders, it will reflect any change in the internal state |
| and includes other events in addition to clicks. "Displayed" means |
| that the control element was meant to be displayed in the controls. It does |
| not mean that the user have seen the element so is not to be confused with |
| visibility. Furthermore, because the controls UI changes while loading, |
| "Displayed" is only computed when metadata are available unless |

| Watch time is defined as the amount of elapsed media time for audio+video |
| media aggregated per player instance. A minimum of 7 seconds of unmuted, |
| foreground media must be watched to start watch time monitoring. Watch time |
| is checked on a regular basis and reported to UMA upon one of the stop |
| events mentioned below or at player destruction if none occur prior. |
| |
| Any one of paused, hidden, or muted is sufficient to stop watch time metric |
| reports. Each of these has a hysteresis where if the state change is undone |
| within some time, the watch time will be counted as uninterrupted. |
| |
| Power events (on/off battery power) have a similar hysteresis, but unlike |
| the aforementioned properties, will not stop metric collection. |
| |
| Each seek event will result in a new watch time metric being started and the |
| old metric finalized as accurately as possible. |
