I can't reproduce this.  I'm also running i3 directly on X (Debian
stable though).  I tried M-x package-install-file RET some-errors.el RET
(see the attached file) then switch focus to a nearby terminal window.
The compile error did not trigger a change in focus.

There have been some changes to the way timeouts are handles, which
could affect frame/focusing stuff (see #24091, #25521, and #29095), but
I don't think it should cause what you are seeing.
