Support CSS hyphens property
The `hyphens` CSS property allows the author to request automatic hyphenation, or to manually insert soft hyphens to explicitly indicate hyphenation opportunities, or to turn off hyphenation. https://developer.mozilla.org/en-US/docs/Web/CSS/hyphens
As of EdgeHTML 16, the ePub viewer inserts automatic hyphens, but with no control (resulting in hyphens where there shouldn't be, like in code). The normal web view uses soft hyphens for manual hyphenation (the default CSS behavior), but does not have automatic hyphenation support. The `hyphens` property is not recognized at all.

IE (and Edge) support hyphens with ms prefix since version 10
