Hmm. Without asking a sighted friend, it might indeed be tricky :(

The normal thing with an HTML select is that you click on it, and the list
opens up, and then you click on something in the list and it closes again
with that thing selected.

The list might well show a visual blank, for example because there is a
blank default option, with a label element associating a label.

In general yes - if you don't want to change the selection, you click
outside the list and it collapses and keeps whatever was already selected.

If what I answered makes sense, then yes…
