Execute Script in Terminal (SSH) not working after upgrade to 2019.2.14.0 64-bit

I have just upgraded to 2019.2.14.0 64-bit, and the "Execute Script in Terminal" function is no longer working for SSH sessions.

I can open up the "Execute Script in Terminal" dialog window, type in the commands and click Execute, but then nothing happens. There is no indication of the commands having been entered into the SSH sessions.

As an alternative, I have also tried putting the commands into a text file and using the "Script file" option, but the result is the same... i.e. nothing happens.
