Bot can't fill <select> fields on macOS

[neopostmodern]

macOS pops open <select> fields when pressing an arrow key, therefore the value doesn't change (<select>s only change when closed)

Problem seems to be that some (?) macOS version now render a even-more-native select pop-up, to which key-strokes can't be send via Electron, at least not the normal way.
