Front-end error when removing options from st.multiselect for certain dataframe shapes

Using Streamlit
1

Hi, I have an st.multiselect with default options used to count a dataset by group and display the summary. When removing options that results in just one row to display (e.g. dataframe shape is (1, x)) I get this front-end error and no error on the terminal.

Front-end error:

TypeError: this.addedRows[(n - this.numRows)] is undefined

Code example:

import streamlit as st
import pandas as pd

st.title('Sandbox')

@st.cache_data
def get_data():
    return pd.DataFrame({
        "remove this option": [1, 1, 1, 2, 2, 2, 3, 3, 3],
        "b": ["R", "R", "R", "R", "R", "R", "R", "R", "R"],
        "c": "B"
    })

df = get_data()

col_opts = df.columns
ColOptsFilter = st.multiselect("Select display columns", col_opts, default=df.columns)

if len(ColOptsFilter) == 0:
    st.stop()  # no columns to display, stop executing

tmp = df.groupby(ColOptsFilter).size().reset_index(name='Count')
st.dataframe(tmp)

I was able to consistently reproduce the issue, but it went away when I upgraded to streamilt 1.45. Maybe related to #10937.
