Description
E.g in the below example the number of facets is not divisible by the number of columns and the bottom row isn't filled up but the xaxes in the bottom row are the only ones where the title is included and where showticklabels isn't set to False.
import plotly.express as px
df = px.data.tips()
fig = px.histogram(df, x="total_bill", y="tip", color="sex", facet_col="day", facet_col_wrap=3,
category_orders={"day": ["Thur", "Fri", "Sat", "Sun"], "time": ["Lunch", "Dinner"]})
fig.show()

Research direction
Start by running the supplied px.histogram example with facet_col_wrap=3 and inspect the generated facet x-axis settings. Trace how the incomplete bottom row is handled when the facet count is not divisible by the column count. Done means the bottom-row axes retain their title and show tick labels consistently with the other facets.
