Reply To: Mobile single page menu doesn't collapse after click on item

As I’ve said I have an issue on mobile view of the site.

Here are the screenshots.
Site before choosing any menu:

When I click on menu button and choose specific menu item the menu still appear on top like following:

I would expect that after clicking on menu item, menu region will automatically collapse, and I’ll see the site contents.
But it doesn’t happen, in order to get back to site, I need again to click mobile menu button and it doesn’t seem to be expected behavior.
I’ve noticed that it happens only with single page scroll menu items. Regular menu links to other pages work as expected.

Please advise.
