Steps to reproduce
Hi, username! > My Preferences > Manage My Pseuds > New Pseud
Fill in the "Name" field with the pseud you want to make, e.g. "testy2"
You'll be taken to the dashboard for the pseud you just created. If you were logged in as testy and created the pseud testy2, you'd be taken to https://test.archiveofourown.org/users/testy/pseuds/testy2.
On this dashboard, the <h2> only includes the pseud, not the username. That means if you're on the dashboard for testy's pseud testy2, it's easy to think you're on the dashboard for the user testy2.
If the pseud has works or bookmarks and you navigate to those, however, the h2 on those pages includes the username and pseud, e.g. "7 Works by testy2 (testy)" or "0 Bookmarks by testy2 (testy)."
What should happen
The dashboard should use the “pseud (username)” format. So if you're on the dashboard for testy's pseud testy2, it should say "testy2 (testy)"
The exception to this is if you're looking at the pseud dashboard that matches the username, e.g. https://test.archiveofourown.org/users/testy/pseuds/testy should only say "testy," not "testy (testy)." If we'd prefer it use “testy (testy),” we would also need to update what is used on the /works and /bookmarks pages.
https://test.archiveofourown.org/users/testy/pseuds/testy2 now says “testy2 (testy)” as expected, and https://test.archiveofourown.org/users/testy/pseuds/testy still says just plain “testy” – looks good!
ETA: Just want to mention that the user dashboard https://test.archiveofourown.org/users/sarken still says “sarken” even when I change the default pseud (not the uesername) on sarken’s account to sarks, so that also looks good!
ETA 2: Also! https://test.archiveofourown.org/users/sarken/pseuds/sarken says “sarken” even when my default pseud is set to sarks, so that’s also good.
Confirm that testy’s testy2 pseud lists username testy2 (testy)
The pseud that matches the username just lists the username.
Also browsed a few other user’s pseuds pages and confirmed it across those as well.
