Minimal PHP Code Causing Issue

Given the following code:

class Bar 
{
	public static function execute()
    {
    	echo strtolower(\Foo\BaR::execute());
    }
}

It got imported:

-<?php
-
+<?php
+
+use Foo\BaR;
 class Bar 
 {
 	public static function execute()
     {
-    	echo strtolower(\Foo\BaR::execute());
+    	echo strtolower(BaR::execute());
     }
-}
-
+}

which cause error:

Fatal error: Cannot declare class Bar because the name is already in use

Expected Behaviour

it should be skipped.
