先前發現的問題

是未能resolve. 不過~有方法可以避開呢。只要利用viewstack ，再自己assign tabBar 就可以了 (簡單來說即是不可以用tabnavigator component 呢，
有方法避開都好。~。)

In this scenario, the textInput doesnt even dispatch click events. But it can still be selected via the tab key.

I found out that this bug isnt present if you use a viewStack with a tabBar. (yipee!)
