Pages are scrollable after reaching a footer

Just noticed that for a desktop version, 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.
