Issue "Last seen" based on start time of search query, cannot be changed for annotations

[simonwh]

What happened:
When querying issues, the "Last seen" always seem to show a value within the queried time frame, not the actual "first seen". In Sentry, the "first seen" always displays correctly as the actual timestamp this issue was first seen (first event in the issue)

When exploring the query sent to Sentry, I see the interval for timestamps set for start and end are very close:

https://sentry.io/api/0/organizations/xxxl/issues/?end=2024-01-15T19%3A56%3A22&environment=production&limit=10000&project=xxxxxx&query=&sort=date&start=2024-01-15T13%3A56%3A22

When using the issues (with first seen) for Annotations, I can't force the start time to be very early (to get the correct data from sentry) without changing the entire time range for the dashboard, which makes it a little useless, since I want to see when new issues occurred, but I can't rely on the date.

What you expected to happen:

That there's a way to correctly get the actual "first seen" for issues when querying them for annotaitons.

How to reproduce it (as minimally and precisely as possible):

1. Add sentry integration
2. Add annotations like on screenshot
