project delete button won't work

I have make a sample testing project to investigate error with `printf` function
https://github.com/denoland/deno_std/issues/2605
but after that when i try to delete it, delete button won't work.

- Project URL : https://dash.deno.com/projects/hungry-dove-31/settings
- Browser : Mozilla Firefox 91.11.0esr

Start by reproducing the failure from the project settings URL in Mozilla Firefox 91.11.0esr and inspect what happens when the delete button is used. No source file or test is named; done means the project can be deleted successfully from its settings page without the reported failure.
