I’ve staged binary hotfixes for 1.15.7, 3.4.5, 11.2.0 and 5.5.1 to work around this issue. The workaround is essentially the WoW process doing the same workaround as
defaults write -g NSAutoFillHeuristicControllerEnabled -bool FALSE mentioned above, but should only opt out WoW rather than every app globally.
I’m not 100% sure when the new WoW builds will get deployed but I’m hoping sometime this week or early next week.
Until then, the workaround mentioned above should be fine. The workaround will also be fine to keep after the WoW patches are live.
If for some reason, the workaround mentioned above is causing issues with other apps, you can run:
defaults delete -g NSAutoFillHeuristicControllerEnabled
in Terminal.app to undo it.
