[lltx] \textit changes font size with LM fonts

[Stephan Hennig]

Hi,

I'm observing an odd behaviour with the Latin Modern Roman and Sans
fonts.  In the attached example the second instance of italic text is
typeset at a smaller font size than the surrounding text.

The problems doesn't exhibit with fonts other that LM Roman or LM Sans
or if either \tableofcontents or \mainmatter is removed.

Can you reproduce the problem?

Best regards,
Stephan Hennig
