Hi I can report this is partially working, at least from my inexperienced opinion.
Site in question (wifes side business)
The “paper options” link in the form needs to anchor to the tabs labelled “paper options”.
The link doesn’t seem to work. Im guessing, but from what i’ve read trying to fix this myself before you released 1.3 it may be because the tab (and therefore the anchor) doesn’t load until needed (clicked). I can prove this: by clicking on the tab manually (then clicking back to another tab) going back to top then re-trying the link which then works.
I hope this makes sense.
EDIT: Interestingly the anchor link works when clicked directly (i.e above) from external website. But not with the page itself. So perhaps my theory is wrong ?
