Autocomplete bug on header search bar

[nickdos]

Not sure if this issue should be in commonui-bs3-2019 or ala-bootstrap3...

Problem: when typing a common name and then using down arrow key to select one of the prompted results, the JS code is substituting the wrong name in - may be an offset issue or one name in list is breaking the code.

Steps to reproduce:
https://bie.ala.org.au/
click magnifying glass icon in header and type into search box gang:

Use the down-arrow key to "step" through the autocomplete results until you get to the result "Ganges goby". Note the search bar now has the value "Tank Goby" and not the expected "Ganges goby".

I've experienced this a few times and it sometimes seems a bit random, with a previous scientific name (e.g. higher in the autocomplete results getting "stuck") being inserted into the search bar.
