popper dropdown on overflow hidden

[pepoospina]

When the popper is inside a place with overflow hidden the popper is not shown if it overflows. Clearly.

However, placing the popper outside the div is very hard. What to do?

This is happening in the dropdown menu of a page item menu on the nav bar.

We can try to use popper.js but I'm not sure it is compatible with the ShadowDOM
