Downloads from Shiny App on text-based browsers fail

Our shiny dashboard works on everything, from IE to Opera, from Safari to Qwant, from Debian Linux to Android (and of course, Firefox and Chrome, Windows and Mac). All screen sizes too, from cellphone to large desktop. That was a pleasure, and we're so thankful for the professional work of the shiny team.

Now, here comes the question: it also almost worked on text-based browsers elinks/links/lynx... but the download buttons failed to download any files. You can check the code in the repository

Does anyone know why, or whether the download in text-based browsers will work eventually?
