IntelliJ cannot resolve FXML Tags
<p>Tags <code>padding</code> and <code>font</code> are unresolved by IntelliJ in my JavaFX project. Everything else works fine.
Plus, these were tags generated by FX-Scene-builder; so I really don't see why there's a problem. 
I have all the necessary imports too.</p>

<p>Here is my fxml-file:</p>

<pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;

&lt;?import javafx.geometry.*?&gt;
&lt;?import javafx.scene.text.*?&gt;
&lt;?import java.lang.*?&gt;
&lt;?import javafx.scene.control.*?&gt;
&lt;?import javafx.scene.layout.*?&gt;
&lt;?import javafx.scene.text.Font?&gt;
