LoadMask in loading image to Img component

[Allan Stark]

ExtJS 4.1.1a
I need to show "Loading image..." mask during update src property of Img component.

This code not show load mask:

certImg.setLoading('Loading image...');
certImg.setSrc('load_image.php?file_name=' + record.get('invoice_item_file'));
certImg.setLoading(false);

And this code show, but don't hide load mask:

certImg.setLoading('Loading image...');
certImg.setSrc('load_image.php?file_name=' + record.get('invoice_item_file'));

I try to increase image size up to 1-2 Mb, this made load it 3-4 sec, but load mask still hide...
I also tried put certImg.setLoading(false) to afterrender Img event, the result was the same.

Does it show if you don't do the setSrc?

Does it show if you don't do the setSrc?

Yes. And when commented "certImg.setLoading(false);" - img is updated, but loadmask still shown over img...

Do not they come across?
Showing masking windos/progress bar is a like a standard situation...
