segmentation - Chart mode 100% is broken

[KerstinFaye]

I started visualizing this chart: https://test.visualize.admin.ch/create/DUpS8om3Nv2R?dataSource=Prod

• Segmentation in Source of emission
• mode 100% --> Visualization is somehow off:

Discussion on Slack: I think we could disable the feature when we have negative values. It would be the checkbox inside editing panel that's disabled? There also could be a situation that user changes some interactive filters and stumbles upon negative values that were not there when chart was created, I think we also should have some error banner that would be shown? Example: https://test.visualize.admin.ch/en/v/pNGoKmtrKZNE?dataSource=Prod and change interactive filter to Balance of land use (not included in total)
