After digging and building, I found out that the pixman library,
which is used by Xorg, is the one which introduced the breakage.

Commit e1dd17451cbe2c7d36205fe2fc4cea0092ee4141 (for the git users)
is the one introducing the behavior.

I have to admit that I'd still be interested in this info...

While I do not see the connection here, this is equally introduced via
the above-mentioned pixman library, namely the commit named above.
