Steps to reproduce:

1. Open this Wikipedia page: https://en.wikipedia.org/wiki/List_of_mathematical_symbols
2. Open FindBar (Ctrl+F)
3. Type the word "phi" (20 matches) or "partial" (34 matches)
4. Try to "find next" (up to the 12 match for "phi")

Looks like some "special character" is blocking the scroll.
