**Steps to replicate the issue** (include links if applicable):
* Create a new user and have this user opt-in to the ReadingLists beta feature
* Then save a page to the reading list (the user's first page)
**What happens?**:
* Hover over the bookmark list icon in the personal tools to see that the url is to Special:ReadingLists and not the default reading list (SpecialPage subpage)
{F68813890}
This happens because when loading the page, the user is not setup yet with a default reading list. In this situation, the code sets the url to the parent special page (Special:ReadingLists) rather than to the default reading list subpage.
For subsequent page loads, the url for the bookmark list icon will work correctly, but we will have the onboarding "saved pages" dialog to highlight the bookmarklist icon after the first save. It would be a bad user experience if the link does not take them to the default list.
**What should have happened instead?**:
Clicking the bookmark list icon should take the user their their default list (if they have one).
- One possible solution could be to use Javascript to update the bookmark list icon url after the user saves a page to their reading list.
- Another solution could be to have the bookmark list icon to link to Special:ReadingLists/{username}/default and then have the special page handle a redirect to the default list if one exists for the user. I think this would be the better solution.
