Anchor points description refers to open() method (should be open attribute?)

[inexorabletash]

https://html.spec.whatwg.org/multipage/forms.html#anchor-points

In the context of the dialog element:

If the value is the keyword 'none', then no explicit anchor point is defined. The user agent will pick an anchor point automatically if necessary (as described in the definition of the open() method above).

... where "open()" links to the definition of dialog's open IDL attribute.

Should this read "the open attribute above" instead?

I think it was supposed to be the show() method. But even then it seems a bit inaccurate. Maybe it is supposed to go #set-up-the-position, which describes various things to do if the computed value of different 'anchor-point's is 'none'.

If I remember correctly, open() was renamed to show() because open was already taken. Seems show() is accurate enough for a note.

We removed the anchor points feature entirely in #2158, so I guess this can be closed now.
