[invokers - interest] What to do with manual popovers on lose interest

[brechtDR]

https://github.com/openui/open-ui/issues/872 gave rise to the potential benefit of a loseinterest option again.

If we would have a manual popover that also gets triggered with interest. What happens when we lose focus? Does it close.

For the moment there isn't something to define this such as a loseinterestaction. Having a loseinterestaction might be too overloaded, but we should at least discuss the possibility, or how we would handle such use-cases.
