Width of text scales based on height of device

Site URL: https://www.othervice.com/

Hi!

So I've got this site where the width of the text changes based on what seems to be the height of the browser when in device view. And I of course don't want that.

It really becomes a major nuisance on certain android devices where you have a home bar popping up in the bottom of the screen when you reach the end of a page, and on certain IOS devices and browsers where both the URL field and home menu shows up on the top and bottom of the screen when scrolling upwards. The end experience for the user being the text adjusting its linebreaks and size whenever you scroll up, making the end user confused.

Any ideas on how to stop the behavior?

It's easily replicated by accessing the site through chrome, bringing up the inspector and switching to device view. Scroll to a text block or title and play with the height of the viewing window. The site is based on "Nolan" fwiw. Also attached a short vid of the issue.
