Could be related to yank-excluded-properties, perhaps? Or maybe you
need to tweak yank-handled-properties?

Thanks for the tip ...

If the above doesn't give a clue,

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

then please explain what you mean by
"the font face is lost".

(I cannot afford repeating your recipe, because it requires installing
weird fonts on my system. Sorry.)

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.
