fix(material-experimental/mdc-list): fix secondary line accidentally wrapping text (#23236)
fix(material-experimental/mdc-list): fix secondary line accidentally wrapping text (#23236)

MDC currently supports three-line list items in a way where
they assume that the second list line should wrap into
a third line. This is not suitable for our MDC-based list
because it would result in an incompatibility with the non-MDC
list and as per Material Design spec it is a supported case
to have a third list line that is decoupled from the second line.

The spec describes multiple variants for a three-line list, and
MDC is not off the spec here, but just doesn't support our
three-line list variant yet. It is planned to continue discussion
with the MDC team to push forward on the other three-line variants.
