This adds significant size to the build. Please [file an issue](https://github.com/lgarron/clipboard-polyfill/issues/new) if you're interested in a minimal build without Internet Explorer support. +- Microsoft Edge (at least version <17) does not write `text/html` to the clipboard using the Windows `CF_HTML` clipboard format ([Edge Bug #14372529](https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/14372529/)), which prevents other programs (including other browsers) from recognizing the copied HTML data ([issue #73](https://github.com/lgarron/clipboard-polyfill/issues/73)). `clipboard-polyfill` currently does not attempt to work around this issue.
