[IOS] When toggled between ion-title and ion-searchbar on ion-toolbar there're shadow root which changed the style

The problem is when I toggled between ion-title and ion-searchbar in ion-toolbar there are shadow root class that remove the padding from the toolbar and it cause the icon to change from its position. It appear only when I simulate the ios device.

The question is, how could I removed this styles from appearing when toggled, or could I edit that style by myself. I try to add the custom class to the shadow root but It didn’t change anything.

Thank you in advance for the help.
