Thanks for reporting.  I've updated the repository so the Mac port
based on Emacs 26.0.90 behaves like the version based on Emacs 25.3
with respect to frame raising.

Note that the flicker/flutter happens even with X11, and with the Mac
port based on Emacs 25.3 running on older versions (< 10.11) of macOS.
Probably newer versions of macOS do some coalescing.

I'll look into it later.
