Some Lightning Web Component attributes are incorrect.

[Paul Kissick]

The lightning-button-menu component has an icon-size attribute, but the options don’t include ‘small’ but is in the documented spec, https://developer.salesforce.com/docs/component-library/bundle/lightning-button-menu/specification

The lightning-combobox component attribute, validity, is marked as required but it’s not. https://developer.salesforce.com/docs/component-library/bundle/lightning-combobox/specification
