The problem occurs in kepubs with all fonts if you make the line spacing close enough, but some fonts allow a closer line spacing than others before the problem starts.

I don't think there is any way to fix this with a patch. My guess is that it is a design fault with the way the KEPUB reader renders pages: it seems like it renders the whole html file at once and then tries to split it into separate pages afterwards. The KEPUB reader is based on the WebKit library which was designed for web pages not ebooks. The EPUB reader does it right, perhaps because it is based on RMSDK which was designed for reading ebooks.

Edit: There is another KEPUB bug which I think has the same cause: If there is a link near the top of a page you can trigger the link by tapping at the bottom of the previous page.

Edit: The Kobo firmware uses a very old version of WebKit. Perhaps the problem will be fixed when they update to a newer version.
