Dear list,

In the latest beta the font fallback using a text font in math mode does
not work anymore.  The log contains messages like

char 𝑐 (U+1D450) in font 'MinionPro-It' with id 8: missing
char 𝑎 (U+1D44E) in font 'MinionPro-It' with id 8: missing
char 𝑏 (U+1D44F) in font 'MinionPro-It' with id 8: missing

which is not surprising because a text font does not have math italics.
How can I get this to work again?  MWE below.

Cheers, Henri
