7.6.3: Clicks on TabSheet tabs causes scrolling?

Vaadin 6 / 7 / 8
1

I noticed some funky behavior in a project and created a simple test project that replicates it. If I have a TabSheet embedded in a layout that has height greater than the screen height (meaning it scrolls), clicking on a Tab results in scrolling.

In the attached screenshots, cap01 shows the top of the layout, cap02 shows the TabSheet, scrolled all the way to the bottom, and cap03 shows the result after clicking to a different tab. I don’t remember this being an issue before. Am I missing something?

I am facing this same issue. Please let me know how to fix this issue as this is very irritating to get the window scroll the very top when I am clicking the tab sheet placed in the very bottom.

Thanks.
