Configurable link field formatter wrongly converts special characters

Problem/Motivation

In the ConfigurableLink field formatter,
When the query string contains one of the following special characters: '&', '"', '\'', '<', '>', they get parsed incorrectly so the output of the query array will contain the textual representation of those characters ('&', '"', ''', '<', '>').

Steps to reproduce

1. Go to any place where the ConfigurableLink field formatter is used, where the target link contains any of the above characters.
2. Inspect the link - the target url will contain the textual representation of the special character(s) instead of the character itself

Proposed resolution

The only solution I saw was to manually search and replace the characters
