add min height to cell outputs

[jonah-iden]

What it does

Adds a min height to cell outputs so that when an output rendering is smaller than that it does not move all the other outputs

How to test

create a cell that does render a too small output. For example i used

import plotly.express as px
import pandas as pd
df =pd.DataFrame({'col1': [1, 2], 'col2': [3, 4]})
px.scatter_mapbox(df, 'col1', 'col2')

create simple code cells below it like print('test').
Execute all cells and validate that the text outputs are not moved into their cell editors space
