Resizing an image to a changed ratio with wp_get_image_editor does not work. Only resizes one side.

I attempted to resize an image from (300w x 225 h) to (294w x 294h) but instead it sizes it to (294w x 225 h).

This is an issue with WordPress as I have ImageMagick installed and when using ImageMagick directly, it properly resizes the image.

Relevant code:

    //This image is 300 x 225
    $image = wp_get_image_editor( "/var/www/wp-content/uploads/2014/03/test.jpg" );

    //I tell it to resize to 294 x 294
    $image->resize( 294, 294, true ); //Passing "false" to crop doesn't help either)
    
    //It saves, but as 290 x 225!
    $image->save( "/var/www/wp-content/uploads/2014/03/test-22.jpg" );

No errors were returned.

Looks like resizing to 294x294 would require upscaling on one side, which we don't currently support.
