What steps will reproduce the problem?
(1) Enter VR Browsing and go to https://rsolomakhin.github.io/autofill/
(2) In the "Credit Card autofill" section, select one of the "Expiry Date:" dropdown list buttons.
(3) Close the dropdown list and click again on the same button.

What is the expected result? List should open again with one click.

What happens instead? See attached video. It takes two clicks to re-open the dropdown list. 

Once the button has the orange highlight, it takes two clicks. If it's not already selected, then one click works.
