Custom event affects bounce rate even when interactive is set to false

[gperriard]

Hi !

I'm facing an issue on a project where the bounce rate is affected by a custom event triggered manually.
The custom event goals is configured in Plausible. It's fired manually on nearly all pages after the basic snippet and with the argument interactive set to false as required in the documentation "interactive - whether to include the event in bounce rate calculations (defaults to true)."

The event triggers correctly, and the interactive is set to false in the HTTP request (i: false).

The bounce rate was low (< 10% over several years).
We removed the event on the 07.01.2026. Since that change, the bounce rate increased to 70%.

I suspect that the event is computed in the bounce rate calculation despite having the argument "interactive" set to "false".

Is there anyone able to reproduce the issue?
