Steps to reproduce:

On a page with a font that ligatures, adjust the content until auto-hyphenation breaks the line between two characters the have a ligature in the current font. For example, 'ff'.

we should expect to see audience-size ef-
fects.

Actual results:

The 'f' on the new line has a ligature as if there was an 'f' on the same line immediately preceding it.

Expected results:

If auto-hyphenation breaks apart two characters that would normally have a ligature, that ligature should not be rendered.
