Sitecore 8.2 update 4

We've been editing some pages, and noticing that rel="noopener noreferrer" get's added into text. I understand that, it's good to have it added to _blank links. But it's being auto-added in text blocks as well when editing.

Ex- I open an RTE field and add new link using "HyperLink Manager" and choose target as a blank. Now save the item and again open RTE field what it did that it added a rel="noopener noreferrer" on link, as well as on above text that is in RTE.

I found a property in Sitecore.config called "ProtectExternalLinksWithBlankTarget" by disabling this "noopener noreferrer" feature is disabled but is there any other way to use this feature correctly.
