url: The URL to open as QUrl or None for an empty tab.
background: Whether to open the tab in the background.
if None, the `tabs.background_tabs`` setting decides.
related: Whether the tab was opened from another existing tab.
If this is set, the new position might be different. With
the default settings we handle it like Chromium does:
- Tabs from clicked links etc. are to the right of
the current (related=True).
- Explicitly opened tabs are at the very right
(related=False)
idx: The index where the new tab should be opened.
ignore_tabs_are_windows: If given, never open a new window, even
with tabs.tabs_are_windows set.
Return:
The opened WebView instance.
