Description: When users insert a merge tag with spaces (e.g., {{ tag.link }}) into the Insert/Edit Link popup for text links, the editor automatically URL-encodes the spaces, resulting in %20 being added around the tag (e.g., {{%20tag.link%20}}). This breaks the merge tag rendering. The issue does not occur in the button link field, which handles the same input correctly.

Steps to Produce:

1- Open the Unlayer Embed editor

2- Add text and highlight a portion to insert a link

3- Click “Insert/Edit Link”

4- Enter a merge tag like {{ tag.link }}

5- Save and inspect the resulting HTML or reopen the link field

Expected: Merge tag should be inserted as {{tag.link}} without URL-encoding

Actual: Merge tag becomes {{%20tag.link%20}}, breaking functionality
