Set Client Configuration timeout seems ignored by prompt:REGEXP usage

I have a CLI application for which commands can take close to 30 seconds. I used the "Read Until Prompt" to determine when the command has terminated and set the timeout using "Set Client Configuration timeout=60 seconds". This works if I specify the prompt using "Set Client Configuration prompt=MyPrompt#" but fails if I do "Set Client Configuration prompt=REGEXP:[$.*#]".

The failure seems to indicate that the "Set Client Configuration timeout=60 seconds" didn't go into effect as the output captured is only partial and the test fails before the expected 60 seconds for a timeout condition (seems to actually fail after 3 seconds which is the Default value of timeout).

I am using robot-framework 5.0.1 and SSHLibrary > 3.2.0 over Ubuntu 22.04 LTS.

Btw, it would be a good idea to add a delay parameter to the Read Until Prompt (and any Read command) as it is available to Read.

Start by reproducing the supplied Robot Framework example with SSHLibrary, comparing Read Until Prompt with a literal prompt and with the REGEXP prompt after timeout=60. Trace the Set Client Configuration and Read Until Prompt entry points to verify which timeout is used, then confirm that the configured timeout is honored for both prompt forms.
