Default Icon show next to icon defined in Front Matter

[pflenker]

Describe the bug
If an icon is set via a custom rule and via the icon property in Front Matter, and if the document is linked using the title property in the front matter, then both icons - the custom rule icon and the one from the front matter - show up.

To Reproduce

• Set up a custom rule in the plugin as described in the docs, matching .
• Create a file, recipes/index.md.
• Set the icon to 🍽️ via front matter, and set up the plugin to look at front matter for icons.
• Set the title to "Recipes" via Front Matter

Steps to reproduce the behavior:

• Link [[recipes/index.md|Recipes]]
• Observe both icons showing up.

Expected behavior

• only the icon defined in the front matter should show up.

Screenshots

Additional context

• Omitting the link text or replacing it with something else makes it only show the correct icon:
