Display names don't show up after account creation

When signing up in Pale Moon and Firefox, display names containing spaces (for example, my real name, Kevin Bhasi) don't seem to show up. I had been taking advantage of the user database being emptied periodically to sign up for multiple accounts using disposable e-mail addresses.

While not visible in the attached screenshot, I created 4 accounts, each in Pale Moon and FIrefox ESR, in both regular and private windows. In all 4, they don't show up.


While troubleshooting, I found that I have to **reload the page** in order to have the name show up.

Possible solution (or at least how I would fix it): Have the Web browser ~~reload the~~ load a new page when logging in and out, which theoretically should also extend to creating new accounts.

I do also have quite a few feature requests stemming from the discovery of this bug, that I'll post a separate (single) issue report for in 1-2 days, and will reference that bidirectionally once that's up.
