Dataframe columns of lists of strings render the strings as ASCII numbers instead of strings #884

When I attempt to render a dataframe that contains a column that is a list of strings (in this case my dataset is called spl and the column is titled team), the strings will be displayed correctly in Streamlit (run locally on my machine) but not when it gets translated using stlite (run using stlite sharing):

spl['team'].iloc[0:5]

Output in Streamlit:

Output in stlite:

When I take the first row of the output from stlite and convert each number into its corresponding ASCII character value,

>>> s = '91,34,83,110,111,114,108,97,120,34,44,34,71,111,108,101,109,34,44,34,71,101,110,103,97,114,34,44,34,90,97,112,100,111,115,34,44,34,70,111,114,114,101,116,114,101,115,115,34,44,34,83,116,97,114,109,105,101,34,93'
>>> s = s.split(',')
>>> c = list(map(lambda x: chr(int(x)), s))
>>> ''.join(c)
'["Snorlax","Golem","Gengar","Zapdos","Forretress","Starmie"]'

It seems that it is able to recognize that spl['team'] is a column that contains a list of strings, as when I run:

spl['team'].iloc[0]

I get the same output for both Streamlit and stlite:
