Region of Static content having in source section HTML code:
<!DOCTYPE html>
<html>
<body>
<iframe src= ABC height = 1000px width=2000px ; >
</iframe>
where ABC is link to page from external application after few iterations shows blank content. It occurs randomly. The link is 100% correct. Being called separately, shows right content.
Have anybody faces such issue. The application is running in Firefox 91.9.0esr (32-bit).
Thanks,
