Currently the incorrect theme is reported in InDesign UXP when using the lightest theme with
document.theme.onUpdated.addListener()
and
document.theme.getCurrent()
You can see from the logs that darkest, dark, light all work correctly, but when clicking lightest, it first fires correctly as lightest, then immediately incorrectly returns to light.
This makes themes incorrect for UXP in lightest mode.
Thanks
