but it didn't. Tried to set yank-excluded-properties to nil with no result.

I attach 2 screen captures to show the problem.

First image is the glyph selection and second image shows that the font has
been lost
somehow ("no font available").

I hope it is not related to my own build with mingw64 but it has definitely
worked with
some previous version of the same emacs-26 branch. Without any other clue,
I'll try to rewind the branch and see if I can track some related change.
