I understand that you find this annoying - I've occasionally seen the issue myself too (I primarily run the IDE on Mac), so I do sympathise.
But as I previously tried to explain, this editor UI update issue is a problem in the Mac version of the underlying Eclipse framework that MCUXpresso IDE is built on top of. It will therefore affect any Eclipse based product from any vendor that uses the affected Eclipse version(s) --> it is not an MCUXpresso IDE specific issue.
Once we migrate to a newer Eclipse version, this should resolve the issue. And until then the workaround when it occurs is at least fairly straightforward. I really hope that this doesn't put you off using MCUXpresso IDE, or NXP MCUs.
