Just noticed that Responsive Web Design doesn't work correctly for a desktop version of website. After reaching a footer with page scrolling, pages of website can be scrolled far further (just scrolling through empty space to the page end). At the same time, for a mobile version everything works fine, page is not scrollable after reaching a footer.
It doesn't matter whether I use native Magento Luma or other theme. The result is the same.
How this issue can be fixed?
Will be grateful for any help.
