no arrow showing up and bouncing on show / hide

[whtFlower]

Hello,

I am trying to use this tooltip for the first time and having some rendering.

Here is what is happening when I use "hint--top" alone.

I have have noticed that hint--top border color not being applied.

when I use hint--always it doesn't stay. Instead it does what I wanted originally. Also when I applied hint--error, the border color get applied.

I am not sure if there is anything I am doing wrong or if it's LitElement which we are using, doing something underneath.

Any suggestion will be appreciated.
