Issue

https://otwarchive.atlassian.net/browse/AO3-4976

Purpose

Avoid highlighting an empty search term, which can split an ampersand entity, leaving a semicolon: &amp<b></b>;.

The minified js file is generated using uglify-js 3.0.12.

uglifyjs public/javascripts/jquery.tokeninput.js -o public/javascripts/jquery.tokeninput.min.js -c -m

Install (vagrant):

sudo apt install npm
sudo apt install nodejs-legacy
sudo npm install uglify-js -g

Testing

See issue.

On any field with autocomplete, search for something with ampersands (usually relationships). The search query should contain extra spaces, example: " term", "term ", "term 1". Without the fix, there will be semicolons.
