Before this commit, search was broken because containsLike was searching on
the innerHtml. (3dd93ed129)
Settings use _wordHighlighter to change the background of the matching text
into the label, so the label was not only text, but html.
<label><span class="highlighter">Mul</span>ti-company</label>
: looking for (mul)
After this commit, the match is based on the text content and not on the html.
