UPDATE: The client has requested testing to disable the click and drag feature in IE, so replicating the bug may be difficult at this time. I apologize if this hinders the community's ability to help fix the root issue.
Here's the issue: It occurs on IE9 and IE8 when the screen height, or more specifically, the browser height is less than the height of the website's main container. The website scrolls horizontally with a total height of around 700 or 800 pixels.
To replicate this bug, open the following URL: in IE9 and adjust the browser height to around 500 or 600 pixels. This will make the page start scrolling vertically from top to bottom.
Make sure you're at the top of the page where you can see the G logo, menu, and social icons. Click in the white area next to the "Our People" section without releasing the click. Then, drag your mouse to the right to initiate horizontal scrolling.
The bug manifests as follows: When the browser height is smaller than the total website height in IE9, clicking and dragging in the middle section to scroll horizontally causes the whole page to jump down vertically, aligning the top of the screen with the "#drag-wrapper" element.
The goal is to prevent this vertical jump while scrolling horizontally. Chrome and Firefox do not exhibit this bug under the same circumstances.
This issue may be related to how IE handles focused elements with specific positioning, given the heavy use of jQuery on the site.
If anyone has any insights or ideas, please share them. I've explored all possibilities I could think of.
