REPL UI bugs in WSL

[alexmalcoci]

I am running a project in WSL using IntelliJ Gateway and I'm seeing a number of bugs with the REPL pane

• The REPL input is only one character high, doesn't extend down.
• There's no REPL history. Up arrow doesn't show previous commands.
• The text doesn't wrap even though 'Toggle soft wrap' is checked. (this one is intermittent)
