file tabs upload bootstrap-4 input-type-file

File Upload Not Working In Boostrap Tab

I am developing a web page where the user needs to upload a file. I am using a general technique that sits on top of the \input type="file"\ element that enables me to style it better.

This works fine until I put it in a Bootstrap 4 tab where it appears that the element stops receiving it's Click event.

To demonstrate this I have an HTML page using Jquery and Bootstrap. I have the similar elements sitting inside and outside of the tab. When I click the 'Browse' button on the elements outside the tab it works as expect. However when I click on the 'Browse button inside the tab nothing happens. You need to select "tab 2" then "tab 1" to get the the first tab's content to appear.

There must something in the Bootstrap tab that is blocking this.

Can anybody point me in the right direction as I need to use tabs ?
