Tab icons hidden when overflow ion-tab border

Hello all! Loving working with ionic. I’m trying to create a button in the middle of a tab bar. In other words, I want 4 tabs (2 left and 2 right) and a button in the middle. And I want the button to stand out by overlapping the top of the ion-tab bar. Unfortunately, no matter how many “overflow: visible” 's I put on classes relating to the ion-tabs and ion-tab elements I can’t get the top part of the button to show. For reference, here is a picture of what I would like it to look like and what it looks like in the emulator currently:
