Disable warnings not working properly?

[Harm10]

I am using version 0.9.4 on RF 4.1.3. I have weird behavior of disable_warnings=1. I set this option on create session together with max_retries=5. To check if I have a proper connection I execute a valid command on get on session. If the connection is bad I get 5 warnings on console before the keyword fails. I can suppress these warnings if I add disable_warnings=1 on get on session! If the connection is OK I get an error: TypeError: request() got an unexpected keyword argument 'disable_warnings'

Looking at the documentation disable_warnings is not allowed on get on session. But I do not want those warnings displayed on console for a bad connection and can successfully suppress them by using this parm on get on session. Following the documentation apparently the disable_warnings set on create session is not inherited for the get on session?

Is this a bug?
