Step's arrow too tall on small screen

[Domin0]

The steps are responsive until they get quite small. Then the arrows are too tall

I've updated my from version 5 to 6 and will test again

It's the same behavior in version 6.0.6

If there are more steps the design seems breaking, especially on arrow theme. Issue still need to fix.
