Copy and paste text link add tags in IE11

[fortunatomaldonado]

Issue

When copying and pasting a link in IE11, the pasted link contains additional tags <u><font>.
https://issues.liferay.com/browse/LPS-87062

Reproduce

I was able to reproduce this behavior in Web Contents of Liferay and in the Document Editor in CKEditor4 using IE11. I cannot test the alloyeditor demo while using IE11.

1. Add some text. "test"
2. Make test into a link with any address. "google.com"
3. Copy the text and paste it below the original text.
4. Look at the HTML of both the texts.

Result
The pasted text will contain tags with a different color.

Original: <p><a href="https://google.com" target="_blank">link</a></p>
Pasted: <p><a href="https://google.com" target="_blank"><u><font color="#0066cc">link</font></u></a></p>

Let me know if there are any questions or comments.
Thank you.
