What Outlook Classic does with overflow-wrap

@emailens/engine 0.18.22 on the original code

Outlook Classic does not support "overflow-wrap". Does not honor any wrapping, including `word-wrap`, `overflow-wrap`, and `word-break`. Using an equivalent MSO breakdown (`-ms-word-break: break-all` and `mso-hyphenate: none` together) does not work.
