Max height as %VH not working on builder side but ok on front side

I have just been setting a column max-height setting to 50vh on a single layout template and in Cornerstone the limit doesn’t work, but on the front side it’s working ok.
See video here

Can you send me a template? I’m not seeing this or it’s not as clear to me in my tests. Thanks have a great day

Added the tco file in the secure note

I was able to replicate this as follows.
Create a new page.
Make a section with a colored background, no padding etc, one row, one column
On the settings for column height, set to eg height: 1000px and then max-height: 50vh or similar.
When entering the 50vh the limiting effect is immediately visible, but upon resizing the browser height no active implementation of the max-height limit is seen.
