Current Behavior

					<IonAccordionGroup value={accordion}>
						<IonAccordion value="first">
							<IonItem
								slot="header"
								color="light"
							>
								<IonLabel>First</IonLabel>
							</IonItem>
							<div slot="content">
								// ... Code with buttons
							</div>
						</IonAccordion>
						<IonAccordion value="second">
							<IonItem
								slot="header"
								color="light"
							>
								<IonLabel>Second</IonLabel>
							</IonItem>
							<div slot="content">
								// ... Code with buttons
							</div>
						</IonAccordion>
						// ... More accordions
					</IonAccordionGroup>

When opening one of them, and clicking on the button inside, it triggers the button's action, but it also closes the accordion. After deeper investigation, it looks like this only happens when the value passed in IonAccordionGroup.value is an empty string.

Expected Behavior

The empty string should be ignored, and the code should work the same way as when the value prop is not passed in.

Steps to Reproduce

1. Use the code provided above.
2. Set accordion to "".
3. Open the
