Cannot call `exit` from within `.on()` blocks

[postmodern]

When I call exit from within an browser.on(...) { ... } block, it generates a weird logging error message instead of exiting. I suspect somewhere in Ferrum it is trying to rescue SystemExit as an error.

Example Code

require 'ferrum'

browser = Ferrum::Browser.new
browser.network.intercept
browser.on(:request) do
  exit
end

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

Expected Result

Exits the script

Actual Result

2023-08-28 04:52:02.989] ERROR -- exit: nil

Version Info

on is happening in another thread, so this might need a documentation and investigation.
