Would you mind to add a unit test?
I think an headless browser will be necessary to archive it, but I didn't do that before

[denis-sokolov]

I could try. Could you assure me you agree with the premise to make the package run in the browsers?

I expect we’ll need additional testing tooling beyond what the project already has. Do you have preferences, are you particularly opinionated about it?

I have used airtap in the past and it works really well.

@mcollina, please release 2.3.0 at your convenience for us to enjoy the browser compatibility. Other outstanding PRs are non-functional from the user’s point of view.
