> Thank you for the issue, and apologies for the delay. I can replicate this, but I need to dig into why exactly it's happening. It's possible this is related to the simulated slots feature that we use for components like ion-input and ion-textarea, since the bug doesn't replicate with non-simulated slots like the ones on ion-button.
