Are datetime-local input types supported in R Shiny at all?

Question

I'm trying to build a custom datetime-local input in the UI like below.

HTML('<input type="datetime-local" max="9999-12-31T23:59" id="test" class="form-control">')

It seems like shiny doesn't even detect this kind of input as calling input$test on the server returns NULL. Is there a way to force Shiny to accept this input type without having to resort to external packages?
