Thanks. I get the highlight — if the second click is soon enough after the first click for macOS to count it as a double-click, thus selecting the text in the field. If you click once to bring up the date picker, pause for a second, then click again, the field is focused but there is not any indication of that.
This is what happens if you pause between the two clicks (first) and if you don't (second):
Another issue is that there is a flashing caret in the field in your GIF of an expiry date being edited, and it's not there in the date field. That makes it difficult to see which is selected if you clicked slowly, or if you started typing then got distracted.
It's also inconsistent having to hit Tab to move between month and year in an expiry date, but having it happen automatically in a date field — I'd prefer the expiry date to move automatically between fields as well.
