I have create a simple search UI with the Text Field and a button next to it. The are the same height on the canvas.
When I run Test Mode on the PC, everything is fine. The FF Preview app renders the Text Field much taller ---> please refer to the screenshots of PC (1) and FF Preview (2).
Another issue with the Text Field is rendering the Label which is clipped by something above the widget. That's screenshot 3.
Any constructive help would be much appreciated.
