Agent Workspace - corrupts SQL

We have turned on Agent Workspace this morning and one of my agents is reporting he is unable to paste in SQL code from MSSQL v18.5.1 in to the Agent Workspace window without it being corrupted.

The code is 

SELECT * FROM AXVC --UPDATE AXVC SET AXVC_STATUS = 'P', AXVC_STATUS2 = 'P' WHERE AXVC_CO = '05' AND AXVC_STATUS = 'N'

 

but appears in Agent Workspace as (the _ symbols have been removed and the test italicised.

However, in the old, non-agent workspace, the same paste action works ok

We have tried this in our sandbox and got same results and also a 'clean' / different browsers.

The only way to get it to work is to surround the code with ```` at the start and end or paste it into a codeblock which adds to the keystrokes needed - which were not needed before.

Does not seem to have affected everyone though.
