Contributor guide
Research direction
Start by reproducing the issue from the Angular Material form-field overview page in mobile Safari 17, using an outline form field and comparing its height before and after entering text. Done means the outlined input keeps the same height with and without text on iOS 17+, with the regression covered by an appropriate project test.
