Nested subplot do not align well in PowerBI Deneb

Question

I tried to make a nested scatter chart using Deneb in PowerBI (Sample Chart), I found that the subplot size will follow the maximum subplot (in this example, subplot B has 4 weather types and subplot A has 3).

I tried "align" : "none" but it did not work, I would like to know if there's anyway to format the chart even if the facet column is not the same, in this example, remove the red frame.
