Why Tooltip in Bootstrap 4 fires once?

Question

css

Hello, I'm learning Bootstrap 4 according to the documentation:
v4-alpha.getbootstrap.com/getting-started/introduction
It says how to connect
v4-alpha.getbootstrap.com/components/tooltips
I did everything. Everything practically works.
The Tooltip only fires on the first hover over the button; on subsequent hover over the button, the Tooltip does not fire.
What could be the problem?

Answer 1

You could at least write a website.

Answer 2

Most likely the button element is rewritten dynamically and the tooltip is not reinitialized. I need to look at the code
