The Shadow presets popover is empty when trying to apply them to a Button block in the Global Style.

It seems this is a core-specific issue, the problem does not affect the Gutenberg 15.1 plugin.

Step-by-step reproduction instructions

1. Activate a block theme (TT3 or other)
2. Go to Global Styles
3. Select Button block to customize
4. Select Shadow property
