bug(autocomplete): text highlighting is broken for escaped characters

What's going on

The issue only occurs when your search includes a special character (ie. <, >, &). It will break in one of two ways:

• When your search ends with &, it will be searching the actual HTML which looks like Alabama & something in this case. It will match the & in & and the highlight <span> will split the special character, causing the results seen in the screenshot above.
• When searching for other special characters, it will simply not highlight anything.

Solution

We need to make sure that we are searching the textContent and not the innerHTML of the element.

@ThomasBurleson Looks like #8368 already fixes this issue.
