Missing CSS property: overflow-wrap

[rushikeshiam]

Description

overflow-wrap is not in the known properties list, causing the following warning:

Property: Unknown Property name. [overflow-wrap]

Background

overflow-wrap was standardized in CSS Text Module Level 3 as the official
replacement for the IE-era word-wrap property. It has been supported in all
major browsers since 2017 and is defined here:
https://www.w3.org/TR/css-text-3/#overflow-wrap-property

Suggested Fix

Add overflow-wrap to the CSS Text Level 3 profile in cssutils/profiles.py:

# CSS Text Level 3
properties[Profiles.CSS3_TEXT] = {
    ...
    'overflow-wrap': 'normal|break-word|anywhere|inherit|initial|unset',
    'word-wrap':     'normal|break-word|inherit|initial|unset',  # legacy alias
}

Workaround

Users can currently work around this by manually registering the property:

import cssutils
cssutils.profile.addProfile(
    'overflow-wrap support',
    {'overflow-wrap': 'normal|break-word|anywhere|inherit|initial|unset'},
    {}
)

Environment

• cssutils version: 2.15.0
• Python version: 3.x
