Bug #86139 Python connctor fails when single stepping in Visual Studio

Description:
Python connector fails when debugging code (Single stepping). Using this code:

import mysql.connector
try:
    cnx = mysql.connector.connect(
        host='XXX.rds.amazonaws.com',
        user='user',
        password='pass',
        database='mydb'
    )

    cursor = cnx.cursor()
    cursor.execute('SELECT * FROM flights LIMIT 0,10', ())
    
    rows = cursor.fetchall()
    print(cursor.rowcount)
    print(rows)

    cursor.close()
    cnx.close()
except Exception as exc:
    print(exc)

Returns results as intended. However, placing a break-point on line "cursor = cnx.cursor()" and running code line by line in Python Tools for Visual Studio 2015, "rows = cursor.fetchall()" raises exception "No result set to fetch from."

Placing a breakpoint immediately after fetchall() (i.e. on printing rowscount) fixes the issue.

How to repeat:
Using this code:

import mysql.connector
try:
    cnx = mysql.connector.connect(
        host='XXX.rds.amazonaws.com',
        user='user',
        password='pass',
        database='mydb'
    )

    cursor = cnx.cursor()
    cursor.execute('SELECT * FROM flights LIMIT 0,10', ())
    
    rows = cursor.fetchall()
    print(cursor.rowcount)
    print(rows)

    cursor.close()
    cnx.close()
except Exception as exc:
    print(exc)

Hello  Justas Poderys,

Thank you for the bug report.
I could not repeat the issue at our end using with Connector / Python 2.1.6 and Visual Studio 2017.
Could you please provide repeatable test case (exact steps/sample code, screenshot etc. - please make it as private if you prefer) to confirm this issue at our end?

Thanks,
Chiranjeevi.
