I have a site that is creating a view with 200 rows of image file names. Each file name has is a link to a reveal modal that displays an image of the file.
Only the first dozen or so rows are shown in the initial viewport. If you click on a file in that initial viewport display, the modal is displayed over the page contents with the viewport contents visiable in the background.
If I scroll down some and click on a file name below that initial viewport list, the modal is displayed as expected, but the background is blanked out after the last row of the original viewport display.
The following screen shot shows the problem.
The code is behind a user log in so it's not easy to provide a working example at the moment. So what I'm after as a first step is to determine if this is a known issue. If it's not a known issue I will move to step two and work on creating a working example that highlights the issue.
