Popover gets closed in Firefox when it contains a select and you click on it

If the popover contains an interactive `` element, when clicking on it in Firefox, a `mouseleave` event is emitted from the select and the popover, which then causes the popover to close, leaving the open select box hanging there on its own.

I have tried to capture the `mouseleave` event on the `select` and tried to prevent it from propagating up to the popover, but it doesn't work.

I know this seems to be a special case, as Firefox is doing weird things, but would it be possible to either not close on `mouseleave` if the target was a `select` or to allow a list of selectors that would not close the popover if `mouseleave` was raised on them.

Thanks in advance.
