Multiple lines of text list column show more/less option not working

UPDATE: I spoke with Microsoft's tech support today after they spent a week researching this issue. They told me that they are not aware of a global issue and can't recreate this on their end. They did a remote session with me so they could see the issue and collect logs to further their research. I suggest strongly that if you are also having this same issue to open a ticket with microsoft. They still don't appear to believe this is affecting more than just me.
