The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Looks like related to beforeunload event

https://modrinth.com/_nuxt/entry.deb546fb.js

  function u() {
    const {
      history: p
    }
    = window;
    p.state &&
    p.replaceState(de({
    }, p.state, {
      scroll: Cs()
    }), '')
  }
  function f() {
    for (const p of s) p();
    s = [],
    window.removeEventListener('popstate', i),
    window.removeEventListener('beforeunload', u)
  }
  return window.addEventListener('popstate', i),
  window.addEventListener('beforeunload', u, {
    passive: !0
  }),
  {
    pauseListeners: l,
    listen: c,
    destroy: f
  }

firingBeforeUnload is true when IsNavigationAllowed is called inside GetCanGoBack

I think i may have some ideas:

1. After clicking the download link , the beforeunload event is calling , so firingBeforeUnload is set to true
2. In the beforeunload event , pushState is called , so Geckoview:locationchange is emitted (with cangoback) , in the message of Geckoview:locationchange , cangoback's is set to false (GetCanGoback returns false because of firingBeforeUnload is true in IsNavigationAllowed )
3. After beforeunload event, firingBeforeUnload is set to false.
