-open-browser=true doesn't work properly on faulty open handlers

[nedsociety]

• Ubuntu jammy, running on WSLg Windows 22H2 (22621.1413)
• xdg-open 1.1.3
• google-chrome 111.0.5563.64, installed via apt
• grpcui 3cc36d3, using go install

Running grpcui doesn't work and the browser keeps trying connection... until you close the browser! If the browser is closed and another is opened then it starts working.

The default open handler is faulty for google-chrome since it blocks until the browser exits. As consequence browser.OpenURL() is a blocking call preventing grpcui process to do its job. A workaround might be to make the call asynchronously.
