HTML doesn't render in checkbox description

[MattMcDowall]

Description

With ipywidgets <8.0, it was possible to include HTML in Checkbox descriptions, and it would render in the display. Now it simply renders as plain text, HTML tags and all.

Reproduce

data = ['Plain text item', 'Item with <b>boldface</b>', 'Item with <a href="http://github.com">a link</a>']
boxes = [widgets.Checkbox(value=False, description=d) for d in data]
widgets.VBox(children=boxes)

Expected behavior

This is how it renders in 7.7.4:

• Plain text item
• Item with boldface
• Item with a link

But after upgrading ipywidgets to 8.0.5, it renders as:

• Plain text item
• Item with <b>boldface</b>
• Item with <a href="http‎://github.com">a link</a>

use print('Item with \033[1mboldface\033[0m') for checkbox Item with boldface

ANSI escape codes may work for the formatting. I can't say, since I've reverted to a <8.0 version due to this behavior; I can say that they don't work in 7.6.5, but I don't care because I don't need them to (since HTML works). In any case, they're no help for links, or any other element that really requires HTML.

I will surely look into it.
