Adding a new tax rate with a long name causes a PDO exception to be thrown on save. This leaves the tax in the listing at admin/commerce/config/taxes without options to edit/configure/delete.
- Go to admin/commerce/config/taxes/rates/add
- Enter in "Scientific and Cultural Facilities District Sales Tax" for the title
- Save the tax rate (and observe the resulting PDO exception)
My guess is that it's related to the machine name that is auto-generated from the human-readable title. The machine name auto-generation script likely needs a length cutoff so the machine name fits in the database table.
