Looks like that's because for CFF fonts, we use the CFFFontName stored
in 'CFF ' table as the PostScript name instead of using the 'name'
table.

Unfortunately for these two fonts, the CFFFontName in 'CFF ' aren't
always correct for the TC variants.

I'm not sure if there is anything we can do here. Force getting
PostScript name from 'name' table?
