// FIXME: Make it scroll to the bottom, using `window.scrollTo()` in the JS above.
// We used to call `m_output_view->scroll_to_bottom();` here, but that does not work because
// it runs synchronously, meaning it happens before the HTML is output via IPC above.
// FIXME: It should be sufficient to scrollTo a y value of document.documentElement.offsetHeight,
// but due to an unknown bug offsetHeight seems to not be properly updated after spamming
// a lot of document changes.
//
// The setTimeout makes the scrollTo async and allows the DOM to be updated.
