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

Start in SeleniumLibrary/keywords/formelement.py at input_password and _input_text_into_text_field, the entry points shown in the traceback. Reproduce the call outside Robot Framework, then inspect the existing form-element keyword tests. Done means Input Password works both with and without a Robot Framework execution context, with regression coverage for the reported failure.
