描述

When using it with custom icons : <ion-icon src="assets/icons/wifi.svg"></ion-icon> Because of the Shadow DOM we can't style at all the content of the SVG. Any custom SVG used is always a square because of the this css lines : https://github.com/ionic-team/ionicons/blob/8c2a507fcff2cb5f2edff60357ffd7feb70bb987/src/components/icon/icon.css#L27-L34 By adding a part="svg" it would be possible to have more flexibility to style the SVG from the outside. In my case setting height to auto, but it could be to change the color of a specific path or anything else.

研究方向
To implement this feature, locate the icon component's template in the IonIcons source code, specifically the file referenced in the issue (src/components/icon/icon.css and related tsx/html). Add the part='svg' attribute to the SVG element inside the component's shadow DOM. Ensure that the change does not break existing functionality and that the SVG is properly exposed for external styling via CSS part selectors. Test with a custom SVG icon to verify that the part attribute is applied and styling works.
