[Bug]: evil-mode cursor rendering desyncs from actual point after activating macOS input method (IME)

[TheWaWaR]

Bug summary

After activating the macOS Input Method (IME) inside a Doom Emacs
session running on neomacs, the rendered cursor stops tracking the
actual point correctly during evil-mode normal-state navigation
(e.g. j/k/w/b). The visual cursor and the real editing
position become desynced. This coincides with the following message
in the terminal/console:

error messaging the mach port for IMKCFRunLoopWakeUpReliable

It's not yet confirmed whether this IMK message is the root cause or
just an unrelated/benign log line that happens to correlate with IME
activation.

Steps to reproduce

1. Launch neomacs in GUI mode (not -nw) with a Doom Emacs
   configuration (default :editor evil module enabled).
2. Open a regular file buffer and enter evil normal state.
3. Activate the macOS input method (IME, Squirrel)
4. Move the cursor with ordinary evil motions (j/k/w/b, etc.).
5. Observed

Expected behavior

The rendered cursor should track point exactly during evil-mode
navigation, matching GNU Emacs's behavior, regardless of whether an
IME was activated earlier in the session.
