Copying a web page link without protocol in a MS Word paragraph leads to a 404 error.

Steps:

1. Create a paragraph in Word and a web page link without protocol (example attached).
2. Copy this paragraph into a Richtext field.
3. Publish.
4. Open that link from the published item in admin panel or on frontend.

Actual: 404 error occurs
in admin panel

Could not find 'location' with identifier '0'

on frontend

No route found for "GET /onet.pl" (from "http://ez2.lh/new-article-1002")

Remarks: When adding a link without protocol directly in the Richtext field protocol is prepended automatically.
