Required tags dialog should set the cursor on the first field when opened

We use the normal tags feature, and a custom tag feature where we tag the customer name. These data are required to resolve a ticket. Annoyingly, the "Tagging required" dialog box supports autofill, but it doesn't default to selecting any field in the dialog. So our team has to use their mouse, and click to open the first tag field, then start typing.

Can you please just activate the first field by default, and allow us to tab between them? That would make it so much faster to send tickets. Today, selecting these with a mouse adds 10-30 seconds to each ticket.
