Is your feature request related to a problem? Please describe.
We could run e.g. js based front end test coverage.

Describe the solution you'd like
Solution / instructions / best practices to install needed plugins and configuration

Describe alternatives you've considered
Cypress as js based framework but Robot framework with browser is cool. Playwright is brilliant base for browser plugin.

Additional context

There is Playwright API for coverage. It is not currently supported by Browser library, but is really interesting idea for enhancement. It also needs some node side dependency handling, most likely we need enhance rfbrowser init command.

As workaround you install dependencies manually and write JS extension to start/stop coverage and report generation.
