Sent mouse events to "duplicate" console not work on remote vi editor.

[zmsunx]

I discovered a strange issue in Cmder. I have "Send mouse events to console" enabled in the Mouse settings, so after connecting to Ubuntu via SSH in the command line and opening vi, I can click the left mouse button to move the vi editing cursor to the position of the mouse cursor — this works fine.
However, the problem is this: when I open a new tab with Ctrl+T and run the same Startup Command, but with "New console split to right", the same operation works correctly — clicking the left mouse button in vi on the remote Ubuntu still functions as expected.
But here's the issue: when I use the keyboard shortcut to run "Split: Duplicate active shell split to right" (Split(0, 50, 0)) to open a new tab (i.e., a new console), after connecting to Ubuntu and opening vi, the mouse stops working. Clicking on a position in the document no longer moves the editing cursor to where the mouse was clicked.
Do you know what the cause of this might be?

Cmder is configuration that ties together several externally developed 3rd party tools.

You are asking about the terminal emulator bundled with Cmder.
