Personal Access Token form - Missing re-populate of toggled scopes, if empty description validation error

[tors42]

Exact URL of where the bug happened

https://lichess.org/account/oauth/token/create?

Steps to reproduce the bug

1. Go to https://lichess.org/account/oauth/token/create?
2. Toggle some scope/s, for instance "Read email address"
3. Do NOT provide a description
4. Click "Create"

What did you expect to happen?

A message about description not being valid,
and any toggled scope/s (from Step 2) to still be toggled,
so that fixing description and clicking Create button is all that's needed to create the token with desired scope/s

What happened instead?

The previously toggled scope/s are no longer toggled.
After fixing the description,
one must notice and toggle the scope/s again.

Operating system

Linux

Browser and version (or alternate access method)

Firefox 128

Additional information

It's an easy mistake after the validation error,
to fix the description,
but not notice that the toggles have been reset,
and then click create which leads to a scope-less token - but one believes that the token has scopes.
