## Bug description

When you create a trend with two lines, one of which is say $pageview with a filter of browser = chrome and the other is ALSO $pageview but a different filter.

If you click on any the line you get the same users in the persons modal, even if you switch the trend line toggle in the modal.

## How to reproduce

1. Create a new trend
2. Add a $pageview trendline, and another $pageview trendline with a subfilter
3. Click on any of the lines
4. Open the persons modal and switch between the trend lines in the persons modal
