Unable to create new community - community name length is max 20 characters - no error message presented when over 20 characters entered ( lemmy.world )

Each attempt to create a new community with more than 20 characters in the Community Name fails.

Community with 20 characters or less in the Community Name can be created successfully.

Actual: If more than 20 characters are entered, upon clicking Create button, the Create button is greyed out, loading icon spins and no community is created. Create button then reverts to normal. No error message is presented on the page.

Expected: (assuming 20 characters is correct limit) if more than 20 characters are entered, display error message / field validation.
