sheet auto width only expands, not shrinks

[LukaPitamic]

Hi, awesome project, I'm using it a lot in fast prototyping UX.

I've just come across strange behavior: https://youtu.be/-6R88EfHeCA

any idea?

Thanks for the report, I haven't seen it before.

Summary: in lab, if you increase the notebook page size, the headers of the sheet grow, but making it smaller, it does not decrease anymore.
