What is the current behavior?

Issue URL: N/A

Accordion related tests were failing intermittently on Safari. Scroll assist adds a cloned input inside of ion-input as part of its adjustment work, and sometimes that would be in the DOM long enough for playwright to pick it up. This led to errors such as the following:

expect.toBeFocused: Error: strict mode violation: "#address1 input" resolved to 2 elements:
        1) <input type="text" placeholder="" autocorrect="off" aut…/> aka playwright.$("input[name="ion-input-11"] >> nth=0")
        2) <input type="text" tabindex="-1" placeholder="" autocor…/> aka playwright.$("input[name="ion-input-11"] >> nth=1")

What is the new behavior?

• Avoid selecting the cloned input in tests

Does this introduce a breaking change?

• Yes
• No
