Colors overlap in Bottom Navigation mode (Transition Glitch?)

[ajitzero]

In the "Bottom Navigation" section,

If I'm on the blue tab and I click on the red tab, then if I click on the yellow tab: there's a orange section on the first part, while the rest is yellow.

If I'm on the red tab and I click on the blue tab, then if I click on the green tab: there's a blue/green/teal section on the first part, while the rest is green.

It's not consistent but does happen with a mix of swiping & clicking on the tabs at either end quickly.

Thanks. I have updated code to fix this problem.
