Huh, what an interesting issue! I think you should open a github issue for this to be followed up on.
If you remove the tags the page resizes back?
Can you please provide a screenshot of how it looks?
I guess I'll have to rerun the experiment without tags for this?
I can scroll sideways but if I open any of the comparison items, I pretty much can only see one experiment's values
