Visit https://docs.python.org/3/library/stdtypes.html#memoryview It says: "Create a memoryview that references obj. obj must support the buffer protocol. Built-in objects that support the buffer protocol include bytes and bytearray." The words "bytes" and "bytearray" are both anchor links. The bytes link points to: https://docs.python.org/3/library/stdtypes.html#bytes If you load that URL in an existing tab, or in a new tab via webkit_web_view_load_uri(), WebKit will scroll to the correct anchor point in stdtypes.html and all is well. But if you Ctrl+click or right click on the link and load it in a new tab via the context menu, the anchor link does not work properly and you're taken to a random point on the page.
