Need to be able to open Dropzone by tabbing into it

[paulhoule]

From the viewpoint of accessibility, <Dropzone> just doesn't exist. I hit tab and it goes right past it. There are ancient answers to this from back in 2018

but these are based on putting an HTML in the label but it seems that the current version only allows a plain text string here.
