SSH LIBRARY: Write keyword failure if text argument has more than 60 characters

Write keyword of sshlibrary is failing if the text argument is greater than 60 characters.

https://github.com/robotframework/SSHLibrary/blob/ac9a92795f94da605f6fd12e5a9716c9931ecd24/src/SSHLibrary/library.py#L1330

Sample xample:
*** Settings ***
Library SSHLibrary

*** Test cases ***
Write Keyword Test
Set Default Configuration timeout=5 secs
Open Connection
Login
${written}= Write echo aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Should Contain ${written} echo aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Close Connection

Start at src/SSHLibrary/library.py around line 1330 and reproduce the failure with the sample Robot Framework test, using a text argument longer than 60 characters. Done means the Write keyword completes successfully and the sample Should Contain check passes for the full echoed text.
