Apparently, styling the toggle as a button caused the additional padding on the left. After reverting to the automatic style (i.e., removing the explicit button style), the toggle looks good, again. One less issue to tackle in @gitlapp!
Strangely, there is now also additional padding to the left side of an activated toggle switch that is styled like a button. I already tried to use a label that only displays the icon but to no avail. 🤔 I am not really sure what is going on here. 🧵 2/3
