----------------------------------------
Hi everyone!
There is an issue with right nav-menu.
Library being used there is called scroll-spy.
https://getbootstrap.com/docs/4.0/components/scrollspy/
I tried to fix the bug with 2 steps:
1) set initial offset position to 10px instead of 0, it fixed the moment of
right menu elements not being highlighted correctly (previously active link was
on upper point of menu)
2) added refresh functionality to toggle method of used library. It fixed the
issue when user clicked on different tabs like JAVA, GO, PYTHON, thus changing
the DOM. This approach was suggested by creators of the library themselves:
When using scrollspy in conjunction with adding or removing of elements from
the DOM, you’ll need to call the refresh method like so:
```
$('[data-spy="scroll"]').each(function () {
var $spy = $(this).scrollspy('refresh')
})
```
It worked pretty much good on localhost, but unfortunately didn't work well
after merging. At this point, we continue our investigation, but if there's
someone who has a better understanding of the root cause any help is very
appreciated.
