EPAM AI DIAL Admin version

Admin: [FE]0.22.0-dev.13 [BE]0.21.0-dev.13

How to reproduce

1. Login to Admin. Open a Test Suite with completed runs and go to the Trends tab.
2. In any Metric Trends chart, hover over any data point except the last one.
3. Now hover over the last (most recent) data point on the same chart.

Actual result

For any point except the last one, a vertical dashed line marks the hovered point (in addition to the tooltip). On the last data point, the tooltip still appears, but the vertical dashed line does not show.

Expected result

The vertical dashed line should appear on hover for every data point, including the last one, consistent with the rest of the chart.
