Empty drop-down menu (Line Height Dropdown Menu)

[Maxx59]

I installed line-height-dropdown-menu then added it to my fixed-toolbar-buttons, but when I click on the line height button the dropdown doesn't appear, there's just a little point

npx @udecode/plate-ui@latest add line-height-dropdown-menu

fixed-toolbar-buttons:

<ToolbarGroup>
      <LineHeightDropdownMenu />
</ToolbarGroup>
