custom tooltip on checkboxes

[epifanio]

Description

Attempting to add a tooltip to a checkbox, I can't modify the default value. The docs claim it defaults to description - but can be changed by using the description_tooltip attribute.

Reproduce

import ipywidgets as widgets
widgets.Checkbox(value=False, description='key', description_tooltip='val')

Expected behavior

toltip rendering the string 'var' and the checkbox label rendering the string 'key' -- instead the tooltip is rendering the string "key" (seems it uses the default value from the description attribute and ignores the supplied description_tooltip )

Context

• ipywidgets version 7.7.0
• Operating System and version: linux ubuntu 21.10
• Browser and version: chrome stable

I'm encountering this issue as well. Is anybody working on this or have thoughts on how to fix it? I've tried poking around in the code but I'm not seeing the solution.

This issue persists in version 8.1.0, even using the non-deprecated tooltip attribute:

import ipywidgets as widgets
widgets.Checkbox(value=False, description='Short descr', tooltip='Some extra explanation')

This gives the following result, when I hover over the checkbox itself or over the text.
