Wrong margin-top calculation on scroll-content with Ionic 3

This is a random issue on Ionic 3. I have no size defined for the header, just the font-size for which I’m using vmax (but I faced the same with px).

BAD (margin-top: 134):

OK (margin-top: 80px):

As you can see both headers are the same. I don’t really need scroll. If I can’t fix this I wouldn’t mind to make the content not scrollable. Is there any defined class/component for this?

@Xiwi did you solve this problem?
