Exceptions within .on() blocks are mysteriously ignored

[postmodern]

I noticed that exceptions raised within .on() blocks are mysterious ignored, and not even logged. This makes debugging errors within other code that's called within .on() blocks very difficult.

Example Code

require 'ferrum'

browser = Ferrum::Browser.new
browser.network.intercept
browser.on(:request) do
  raise("error!")
end

browser.go_to('https://example.com')
sleep

Expected Result

An uncaught exception being raised.

Actual Result

Nothing

I believe it's ruby-concurrency/concurrent-ruby#634 but I never had time to work on it.
