Describe the issue:

xarray datasets have a bit of a quirky behavior when printed to the Python console as in:

Steps to reproduce the issue:

Send the following code to console, or enter it directly:

import numpy as np
import pandas as pd
import xarray as xr

np.random.seed(123)

times = pd.date_range("2000-01-01", "2001-12-31", name="time")
annual_cycle = np.sin(2 * np.pi * (times.dayofyear.values / 365.25 - 0.28))

base = 10 + 15 * annual_cycle.reshape(-1, 1)
tmin_values = base + 3 * np.random.randn(annual_cycle.size, 3)
tmax_values = base + 10 + 3 * np.random.randn(annual_cycle.size, 3)

ds = xr.Dataset(
    {
        "tmin": (("time", "location"), tmin_values),
        "tmax": (("time", "location"), tmax_values),
    },
    {"time": times, "location": ["IA", "IN", "IL"]},
)

Expected or desired behavior:

In VS Code, (Jupyter Notebook) the output looks like this:

Notice how some drop downs are darkened if they can't be expanded, but all with content can be expanded. Additionally, in Positron when expanded, drop down titles disappear.

In Python Console from system terminal:

>>> ds
<xarray.Dataset>
Dimensions:   (time: 731, location: 3)
Coordinates:
  * time      (time) datetime64[ns] 2000-01-01 2000-01-02 ... 2001-12-31
  * location  (location) <U2 'IA' 'IN' 'IL'
Data variables:
    tmin      (time, location) float64 -8.037 -1.788 -3.932 ... -1.346 -4.544
    tmax      (time, location) float64 12.98 3.31 6.779 ... 6.636 3.343 3.805

Were there any error messages in the UI, Output panel, or Developer Tools console?
