Regression: y-axis minimum is ignored for stacked histograms

[Caerbannog]

Part of the problem persists.

I have tested Metabase v0.50.12.
The fix works for stacked histograms.
The fix does NOT work for "stacked - 100%" histograms.

To Reproduce (steps 1-3 are the same as before)

1. Create a new SQL question with the code below:

select 10 as y, 'xx' as x, 'a' as split
union all 
select 15, 'xx', 'b';

2. Click on Run, set the vizualization to "Histogram"
3. Configure the series as below

4. Now go to the "Axis" tab, uncheck the automatic Y-axis scaling. Set a Minimum of 0.5, a maximum of 1.5.

5. Go to the "Display" tab and select the last stacking option ("Empiler - 100 % (Diagramme à bandes en fréquence)" in this screenshot).
   What should happen : the Y-axis should start at 50%, NOT 0%. This used to work.
