No. It means that the fix is a lot simpler - return early in markForSync if the syncTimer is already active.
Something like

if (syncTimer.isActive())
    return;

You also might want to stop the timer in ::syncLayers.

The bug is actually that we rely on Timer::startOneShot to do nothing if the timer is already running, but that's not how Timer::startOneShot works.
