Ionic v4: After changing tab text, how do you recenter it?

I change the name of my “account” tab dynamically when the user logs in. If the two texts aren’t the same size, the new text isn’t center. I made a StackOverflow post about it (I’ll go here first next time, this is my first post here). I appreciate any help.

Edit: Someone answered it on stack overflow. It can be done in CSS. However, it also auto centers if you upgrade >= Beta 15.
