Dock icons stop bouncing when, loosely speaking, the process starts up its
macOS-style event loop (and could then e.g. respond to quit requests from
the Dock). X11 apps never have that type of event loop, so the bouncing
will not stop.

The only fix I know of without modifying the programs is to use a small
shim process which either
(1) "is a proper Mac app" (setting up the event loop and perhaps doing
niceties like converting macOS quit events into signals) or
(2) forks the real process and immediately exits (which means the Dock icon
also disappears).

(Disclaimer: I am more "power user" than "macOS developer" today and my
description may be inaccurate in the details.)
