Default PreventUIRefresh while deferred script is running

I would like to prevent UI refreshing (in the arrange window) while a deferred script is running in the MIDI editor. (In the hope of improving the speed of the script.)

I have tried setting reaper.PreventUIRefresh(1) when the deferred script starts, and then reaper.PreventUIRefresh(-1) when the scripts eventually exits, but this doesn't seem to work. (Nor if I use any other integer.)

According to a post in another thread:

The fix aims to prevent that.
This prevention system also seems to override PreventUIRefresh in deferred scripts.

So... is there any way to prevent UI refresh while a deferred script is running?
