Tabs dont work

I have problems using tabs in my ionic application. The user can select items from a list or from a map. When an item is selected a ItemDetailPage is shown.

Problem:

Serving the application using ionic serve everything works fine. When creating the application using ionic cordova build browser and deploying it on a webspace im running into the following issue: The tabs / switching tabs dont work in the DetailPage when the user selected the item from the map. Whereas when the user selects the item from the list everything works. When debugging the website with web developer tools and tooggling different devices the previous click on a tab is exectuded and the tab switches. Very wired! Any ideas?
