Flexdashboard opens new tab with every user input

I would like to ask for help with a Flexdashboard using Plotly and Shiny. The only thing now is that the app is throwing away browser tabs like there's no tomorrow. For every reactive input from the user, the app opens a new tab, where it does produce the correct output.

I've noticed that Flexdashboard, Plotly, and Shiny all work well for me. The problem seems to arise somewhere in their combination.

I would greatly appreciate some advice. The reproducible .Rmd script may be found on Github here. It was deployed in about two minutes by using the code below:

rmarkdown::run('complete norms flex.rmd')

Below is the output I got (which didn't reveal a lot to me).
