Lightroom SDK: preset:getSetting() returns all develop settings, not just those of the preset, breaking plugins

In LR 7.3.1, preset:getSetting() returns all develop settings, not just the settings actually changed by the preset. This breaks existing plugins.

For example, the .xmp of a preset that changes just Exposure contains just the Exposure2012 develop setting:

   crs:Exposure2012="-0.12"

But preset:getSetting() returns all the develop settings:
