event.preventBaseUIHandler is not a function

[aarongarciah]

Bug report

Current behavior

Calling event.preventBaseUIHandler() inside some event handlers yields an error although the types say preventBaseUIHandler exists:

event.preventBaseUIHandler is not a function

Some examples of event handlers that have wrong types:

• MenuItem: onMouseDown
• MenuCheckboxItem: onMouseDown
• MenuRadioItem: onMouseDown
• MenuLinkItem: onMouseDown, onKeyDown, onKeyUp
• AccordionTrigger: onMouseDown, onMouseUp

This is probably a general type problem affecting event handlers in many components.

Expected behavior

Either update the types to remove preventBaseUIHandler from the relevant types or include preventBaseUIHandler in such events, but the latter probably doesn't make sense if the event handler in question is not doing anything on the Base UI side.
