Discussion in the GRUB project; they've decided not to fix this in their
code and to instead wait for it to be fixed in flex:

http://lists.gnu.org/archive/html/grub-devel/2017-02/msg00133.html

flex discussion:

https://github.com/westes/flex/issues/162

So, the flex package on core-updates is not ready to be deployed,
unfortunately :(

We can wait for a flex update or try to port the bug fix.

Any volunteers?
