Comment:

 Confirmed. Also happens in Edge on Win10. Similar to the cruft that Chrome
 inserts but only when pasting links (fortunately).

 The good news is that we already have filtering on paste for Chrome/WebKit
 what we can also turn on for IE/Edge.

 The bad news is that Edge is can also insert other tags without inline
 styles, in particular seeing `<u>`. The only thing I can think of is to
 strip all `<u>` wrapped in links.

 This will remove the `<u>` even if the original content that was copied
 had that tag combination. However it seems better to "clean up" such
 cases.
