Javascript error with UTF-8 (Arabic) search

The on-page search works perfectly on English pages on the sites I manage; however, on Arabic pages it fails with the following console error:

codepeople_shearch_in_place.min.js?ver=1.1.4:25 Uncaught DOMException: Failed to execute 'splitText' on 'Text': The offset 169 is larger than the Text node's length.

Generally speaking, it gives this error for words greater than 2 characters with varying offset values. Longer words will work if they only appear once on the page. For example:

• This works: ما هو (two words of 2 characters)
• But this does not: على (3 letters)
• However, this does: الخروج (appears once)
