Chromium process left running after running all tests

[ankur22]

Brief summary

After running all the tests, chromium browser processes are left running, even when all tests pass. I've looked as far back as v1.6.0 of xk6-browser and the problem still exists.

xk6-browser version

v0.53.0

OS

NA

Chrome version

NA

Docker version and image (if applicable)

No response

Steps to reproduce the problem

Run this from the root of the project:

go clean -testcache && go test -v -p 2 -race -timeout 240s ./...

Expected behaviour

Test passes/fails but no chromium process found with at the end of the run:

ps -ef | grep "k6"

Actual behaviour

After the tests pass/fail left with running chromium processes:
