Focus sends duplicate event pings

[st3fan]

On backgrounding Focus 3.8, I see the following requests being made:

   POST https://incoming.telemetry.mozilla.org/submit/telemetry/E2EC17B2-0D3B-42A8-BB3F-37C38E97D65C/core/Focus/3.8/release/unknown?v=4

        ← 200 text/plain 2b 170ms

The last two requests have the same content:

So should this be a Focus iOS issue or is it a Telemetry issue? Hopefully the latter and Focus gets a free fix. Also who will work on this?

My guess is telemetry lib. I don't see this on the dev branch. My hope was that we would show the latest dev version working well in today's beta, but someone hooked it up wrong (me). Tomorrow's beta should demonstrate this.
