Option to automatically close Popover when another overlay opens

[rolfsmeds]

Describe your motivation

In some use cases, you want Popover to close when any other overlay opens (e.g. DatePicker dropdown, another Popover, Dialog). Rich tooltips opened on hover are a good example of this (it seems that mouseout closing isn't reliably triggered in this scenario, which exacerbates the problem).

Describe the solution you'd like

An opt-in automatic closing of a Popover whenever another overlay opens.

Tooltip has this mechanism by default (

web-components/packages/tooltip/src/vaadin-tooltip-mixin.js

Lines 653 to 662 in 570c0e9

	__onOverlayOpen() {
	if (this.manual) {
	return;
	}
	// Close tooltip if another overlay is opened on top of the tooltip's overlay
	if (this._overlayElement.opened && !this._overlayElement._last) {
	this._stateController.close(true);
	}
	}

).

E.g. setCloseOnOtherOverlay(true) / close-on-other-overlay
