Selecting the tom select option in the dropdown often happened quicker
than the search finished. In that case we selected the option from the
list of all options and then the search would present the found option
again and leave the dropdown open.
This didn't cause any trouble in the past because any other action would
close the dropdown again. But the new cuprite version didn't trigger the
next click on the target element. It would just close the dropdown on
the next click without further action. That would then break the next
assertion looking for the next open dropdown, which didn't open with the
click.
Selecting the "active" option means that we wait for the search to
finish and present an option as active. Clicking that option closes the
dropdown without opening it again.
