The RadBinaryImage in our application works well until Firefox upgraded to 43.0.1. Now the problem I am facing is that the image does not show unless I click or move the mouse on the page. I also noticed this issue only happens on gif files, not on jpeg files.
Here is the scenario: two pages included in this test demo, the first page has a linkbutton to open a radwindow, the second page is the RadBinaryImage to display a image file.
The following is my test code, please help, thank you.
