I am scratching my head on this one. I develop the app on Windows, but when the app is accessed on macOS, the height of the buttons is not the one defined in the inspector. For example I set the height to 50, but the height I get is a little bit higher than the text, as if the height is predetermined and can’t be set on macOS. I get that in Safari and Chrome as well.
Also, remember, it’s the web. Things will get rendered differently Mac, Windows, Linux, Safari, Firefox, Opera, Chrome, Edge, IE, Brave… and so on. The best thing to do is avoid doing anything non-standard. Leave control defaults as they are or risk breaking things.
