Expected behavior and actual behavior

Keyword Input Password works with and without Robot Framework

Environment

Browser: default by Open Browser keyword
Browser driver: Gecko
Operating System: Windows 10
Libraries

• Robot Framework: NOT USED
• Selenium: 3.141.0
• SeleniumLibrary: robotframework-seleniumlibrary==5.1.3
• Interpreter: Python 3.7.5 | packaged by conda-forge | (default, Jan 28 2021, 18:15:34) [MSC v.1916 64 bit (AMD64)] on win32

Comienza en SeleniumLibrary/keywords/formelement.py, en input_password y _input_text_into_text_field, los puntos de entrada que se muestran en el traceback. Reproduce la llamada fuera de Robot Framework y, después, inspecciona las pruebas de keywords de elementos de formulario existentes. Se considera terminado cuando Input Password funciona tanto con un contexto de ejecución de Robot Framework como sin él, y existe cobertura de regresión para el fallo indicado.
