/**
* Autocomplete/Dropdown list
* Uses https://yuku-t.com/textcomplete/
*
* Notes:
* - Won't work with CodeEditor since it doesn't use a textarea but that's fine
* since CodeEditor won't be used for wikitext
* - $.getScript() is used since mw.loader.load() doesn't wait for the code to load
* mw.loader.load('https://unpkg.com/textcomplete@0.13.1/dist/textcomplete.min.js');
* Bugs:
* - The regex fails if there is an instance of {{Color| before it in the textarea? tho it's fine in the example webpage
* - In addition, whenyou start a "{{Color|", then pop over to a different "{{Color|", it'll show dropdown, but append to the first "{{Color|""
*
